I came here to ask a question of a larger group of people. I have asked this of my family and friends, and nobody seems to experience the same vividness that I do.

As I am falling asleep, a lot of the times, I will see random images, still or animated. They are VERY vivid as though I am there. I can't seem to interact with them, but I can somewhat control the direction that they take, as they change as I am lying there. I can clearly look around and see every detail in the area.

About a week ago, I experienced a new type of this .. as I was falling asleep I heard some orchestra music playing. I could hear different instruments, it sounded as though it were right in my bedroom. I heard it for about a minute (guessing) before it woke me up enough to check if the alarm clock radio had gone off or anything.

Has anybody experienced anything like this before? To be clear, I am not asleep and dreaming as I can think at the same time. I often see these pictures when my mind is most active thinking of a programming problem i've encountered or something similar.
