Sorry if this is a subject you have already discussed, but i didn't find it and i'm curious about this.
I believe this happens to you all the time. I was trying to sleep, then, all of a sudden i felt my body heavier and started to enter a dream (i believe this is WILD). But i wasn't in a new environment. I was in my room, in the same place and position i slept, in my bed. My room was exactly as it is, but a little different. The walls had some huge blisters coming out of it. My lamp was lit but misplaced. I looked at my arms and they were long, thin, with huge veins popping out and only 3 fingers. I then started to hover around in my room, but still paralysed in the same position (like there's no gravity).

What kind of dream was this? How come it wasn't like other normal dreams, i mean, popping up in some environment and situation my sunconscious creates? Was this some kind of "lucid dreaming meets astral projection"?
It's so curious how the subconscious created the same place i was in. It was like i didn't enter a dream, but instead i went to a special mental state that gave me a special vision of the real world, like seeing elements from another dimension inside ours. Sorry for this description, you may find it a little absurd, i guess. :p
