Hey everyone, this is my second research round with my question "Why do we dream?". This cycle I will be looking into the different kinds of dreams.


What are different kinds of dreams?

A dream while you sleep- I’ve already defined this in my first research round but in case you need a recap, a dream is are imagery and images we receive while in certain stages of sleep(1,2,3,4,9). There are no limits of what we dream. Dreams can literally be anything and there is no real limit. Majority of the time, dreams occur during REM sleep. (1,9)

Lucid dreams-  Lucid dreaming is when you are consciously aware while you are dreaming. You get the ability to control or observe your dreams consciously. It makes your dream world feel like a reality, everything you feel, hear, see and smell feels like it’s real life. In regular dreams, your self awareness is shut down which explains why dreams can be hard to remember and feel fuzzy. However in lucidity, it occurs when your brain is between stages of consciousness when your brain realizes that you are dreaming and switches to waking mode while you are dreaming. (5,9)

Daydream-  Daydreams are a form of altered stages of consciousness. Consciousness is our level of awareness of what is going on around us at all times. Most of the time, our conscious levels are changing throughout the day, and we usually don’t notice when it changes. The brain likes to do things without us noticing or having a say. Daydreams actually however help us change into an altered state within a second. Daydreams don’t require much either. Taking away the slightest bit of attention can make us start to daydream as well.(6,9)

Nightmare- Nightmares are dreams that have imagery that gives fear, sadness or anxiety. Most people remember nightmares because it often happens later in the night which wakes the sleeper. Most nightmares are your brains reaction to stress and some suggest maybe even to help people through traumatic events. (7,9)

False awakening-  A false awakening dream is when in your dream, you’ve woken up and follow a continuous cycle of doing one thing, for an example, waking up and falling into a hole immediately and just a continuous cycle of doing that.It can be extremely frustrating and annoying. In a false awakening dream, you’re thinking clearly and that causes you to assume that you are awake. The truth is you are not awake, you are only aware. False awakening dreams can be related to lucid dreams as you are aware in both. (8,9)

For my next research round, I will be looking into sleep disorders and how they affect our dreams.  Thanks for reading!

Original Post

Hi Rhéa!

Wow great post! I didn't know that there were that many different types of sleep! Dreams are such an interesting topic because they show that our brain can generate itself a whole world of "conscious" experiences. As you said, in daydreaming, the brain likes to do things without us noticing or having a say. It's said to be also a useful process for our minds. That is a concept that find fascinating. Typically, whenever my minds wanders off, I don't find it working to my advantage. For example, when someone is talking to you, you don't really want your mind to randomly start thinking about what you ate for breakfast.

Nonetheless, you may be interested in researching how sleep effects us mentally and physically. I was just looking at this website (that is now listed second in my suggested websites you can take a look at) that says that nightmares, for instance, reduce psychological tensions by letting the brain act out its fears. There was this study that found that people who were distressed in their dreams have reported general anxiety than those who experienced an upsetting event occurred to them already. As a result, they think that it's because that for those people, normal emotional processing during dreaming failed! This is actually quite interesting! Obviously, stressful experiences cause nightmares. However, its found that nightmares diffuse that tension! Consequently, people who have difficulty sleeping have an easier time dealing with emotional ordeals. Think about that for a moment. Nonetheless, there are so many effects of different types of sleep we get! It would be intriguing if you were to do some more research on that. You can also take a look at how it effects our emotions as well as the amount of sleep we need to function well. My second research round is quite similar to your inquiry question, so I remember looking into Sigmund Freud's theories of consciousness. I believe if you get a higher understanding of how our awareness connects with our unconscious sleeping hours, you would be able to enrich your cycle. You should take a look in that!

Here are some websites that may help you on your next research round:





Good luck. I can't wait until your next round!


Hey Rhea, 

Interesting round on different types of dreams that take place! I found day dreaming particularly interesting since I tend to daydream quite often, but I never knew day dreaming was considered a change in consciousness. Perhaps during your last round of research you could look into common misconceptions of dreams such as "not everyone dreams" and "dreams are uncontrollable". Also maybe you could investigate if sleep walking and talking have any connection to dreams. Anyways here are some links for your next round of research and I'm looking forward to reading it. 




Hey Rhea!

I really enjoyed reading this post, because just the general view of dreams and sleep has always interested me! I've heard of these types of sleeps and dreams before, but now I have a clear understanding. I didn't know that lucid dreams occur when your brain is between stages of consciousness! I'm super excited to read your next round of research. 

Maybe for your next round of research, you could include the varying age groups and their most common sleep disorders? Here's a site that you might find useful. 


Best of luck!


Hi Rhea,

Nice research! It was neat and organized, and I liked how you provided a diagram that explained the circadian rhythm cycle - that was helpful. I found the part about false awakenings fascinating, as I don't believe I've ever experienced it before. Another thing you mentioned that I found interesting was lucid dreaming. Did you know that lucid dreaming can lead to sleep paralysis, where you are conscious and awake but cannot move your muscles (from what I've heard)? I don't know a lot about it, but if you're interested, you could look into that.

Here are some websites you can use for your next round of research:




Good luck!

I really like your use of images and diagrams to help explain the different types of Dreaming.  The role of dreams in helping people work through or process thoughts makes sense. It would be interesting to learn more how we can help support this process, techniques to support dreaming and to learn from the dreams to help reduce anxiety or effects of trauma.




Hi Rhea! Nice research. I can see that you go over different types of dream, but I am thinking that you can compare the heart rate between these different type of dream.
