I am like this too I often say to myself before dozing off where are we off to tonight!
I love my dreams they are so realistic at times. The thing that fascinates me most are the places and faces that appear in dreams. Yes you have family, friends and famous people from time to time and places you have visited. However a lot of the time it is complete strangers and locations. Where do they come from is it people you pass in the street and your mind adds them in. Is it places/faces on TV or Movies?
When I think about these things I then question how people who are blind from birth have dreams too.
The mind is an amazing thing!
