Some medical experts who have written on LSD and other hallucinogens have taken
some interviews where people have observed a merging of their sensory inputs: sight,
sound, smell, taste, etc.
I myself have experienced an astral travel experience where up waking from a dream
(I was concious yet I could see my body on bed because I was floating on the ceiling).
Later, I have learned this is lucid dreaming. You could say I dreamed I was dreaming.
However, I was concious within the dream. I was 15 when that happened. It has
affected my life in the way I more open to consider that little is understood in the way
things really work. This is what makes it exciting!
