I have lucid dreams on a daily basis, which to be honest covers most of the points in the poll above.
Dreams often come related to new memories, or how i am feeling in that timeframe.
This kind of (on a non-sustential basis) confirms the idea that the functions of sleep is to reprocess memories (short to long term storage, kind of like saving your ram contents to a harddrive)
If i am feeling down, i will dream of soothing things - which also differs in itself. Like i can picture a person calming me, or simply having a dream where i do some awesome skiing.
So on, and so forth (with emotions)
Then theres the "scary" or "evil" dreams. My problem is that after the military i wasn't really afraid of dying (you should experience what this does to your fears) - so i cant really picture anything i am afraid of in my waking mind.
Of course certain social situations amongst other things, but its not really fear - its not like i am afraid of it, i just dislike it.
However, in my dreams i am just very, very afraid. No reason attached.
Which doesnt really make sense, because the reason someone is afraid is because they are (potentially/believe they will) moving from a positive to a negative state.
Then theres the social dreams, they are very much like the "evil" dreams except i cannot categorize them as such.
I can wake up and be 100% sure i have had a conversation with someone about something, but when i ask that person about it - they have no memory of it.
So my mind sort of plays me here, and this really scares me (mmhm). Have you seen old people with dementia?
I also have functional dreams - where i find the solution to problems. I cant really wrap my head around these, so i wont write too much about them.
Finally theres the dreams i can control. I can somewhat control the dreams mentioned above as i am playing around in them, however i am not aware of doing so until i wake up.
These dreams are wierd man.
Often i put myself in a situation where i have control of a plane 2d or 3d. I tried 4d, but that didnt work
Then i can more or less create anything on that plane. - It has to be from an idea, and i can only do major alterations.
I can for instance create a model of the Eiffel tower, but i cannot put a person besides it, if i do then either one of those becomes a blur.
I can create a city, but i cannot control an individual structure in that city. If i change one of the structures, then the entire city changes.
Anyway, these dreams hurt if i go on for too long. It physically hurts. It starts with a sort of chemical taste, then after a while it hurts like if you were to get an electric shock. So i do try to avoid these.. its kind of fun though
This stuff is just too crazy to talk to any sane person about, so i haven't really talked about it for length before. Only mentioned a few points in a passing conversation or something like that.
