It may be, but no clear reason to think it may not be otherwise. Is the programme you watch on the TV just a product of the TV set ?
I may not recall where I was while asleep, but there again, I don't recall where I was this day say 7 years ago. Memory is a strange thing. Apparently most is just reconstructed anyway. One thing I'm sure of, reality, whatever that is, will be much stranger than we can presently imagine. One only has to compare quantum theory and even more cutting edge conjecture with that believed in, in the Middle Ages, to get a taste of how little we really know.
