In the past I have had similar experiences but been "too afraid" to actually let the feeling continue to the point where I felt lifted out of my body. A pretty bad mental block. So I have been waiting to re-experience this for a while now.

I have done very light research on the subject and it did seem to me that it could have taken place in an "astral realm" vs a dream space.

I do believe there is a strong link between A.P. and L.D. and think that they may even take place in the same "space". I think that possibly the difference is the entry method.

What I think I experienced is similar to what some people experience through certain types of drug use however I was in control of my self, not the drug as I was not on anything.

It is interesting to see you use the term "training space" because I was reminded of being in a "sandbox" mode of a game without any boundaries or rules. Since it was my first time in this state I had no idea how to even manipulate things so I was like a child. I am a painter so my instincts told to try to manipulate the colors like with a paint brush.

It was by far the strangest experience I have ever had.
