Nice leads, but most of all I like the ambient background sounds. It sounds like you put more work into the background than the instruments you put as the primary focus. Maybe switch the focus between the lead and one of your background instruments throughout the song intermittently? Maybe that would be cool. Another thing that can sometimes sound cool especially for claps is to have a short lead-in sound right before the clap like a soft reversed snare or a noise ramp.
Interesting title too, I'm putting 3.5 mostly because it sounds like an incomplete idea however I guess that would make sense considering you say it's from a dream, very curious process there.
cheers for the review mate! :P
