Dreams are recollecting the dream

To me there are two kinds of experience in dreaming.

First there is the regular dream. It has no control. All my actions in it are already dictated (it is like I am remembering what I have just done in the dream) and all the impressions and thoughts I have in the dream are like the ones I would present in waking experience, reflecting my regular limited being. The experiences also reflect the ones I would have and had in real life. This is the usual regular dream, after a long sleep (full cycle) and the recollection o the dream scenes comes in streams at the end of the cycle.

The other experience is the one of not going for a complete regular cycling sleep(with REM, and etc,) but a small one. I get asleep and suddenly (and literally) am in somewhere else. Sometimes it is all dark, sometimes is the house I live, sometimes is a different house. It is like I have the body in that dimension, and I have to focus to not make it slip away. There I can float around, touch objects, interact with people that may be there, do anything if I truly and naturally want to. This experience takes 30 minutes between sleep and awakening.

These are the most regularly occurring of the dream experiences I am used to have. Of course there are many other kinds and possibilities (divining for example) and they are related to greater mastery of dream states.

I am pointing here to the relation between dream states and the stages of sleep. I believe dreams occur in the deep sleep where consciousness (usually) cannot dive into. Then when we are coming back to waking state some mechanism in our being start recollecting what we saw and experienced in the deep state, constructing the scenes with images made by bits of memories of waking life. Then just before waking from sleep is the moment of maximum of remembering and after this the very memories of dream start to fade away. This occurs if we don't train to remember, but mainly(to my opinion) if we do not have a great relation with the unconscious. This made up experiences are at the same time similar and of a different level of real waking experience. Since they have no practical utility in the waking life (as we usually live) they fade away.

Any thoughts people? Please share any similarity or disagreement in your own experience.
