Ok.. This has happened two times
If I fell asleep after listening to this I have nightmares.. Why?
Dreaming (and nightmares) are your brain's way of dealing with the challenges and frustrations of life. Unless you've suffered particularly heavy emotional trauma (such as battle-related PTSD), the nightmares should fade after a few nights.
That said, this track shouldn't be long enough for you to get into heavy serious dreams ... and it's intended for use in the middle of the day. :)
