I'm big on meditation probably an hour or two or three a day. I've been seeing a lot of Blue lights lately...sometimes they are little dot lights or blue hazes. anyone notice this too?

Dreaming..i seem to get in the Hypnologic imagery right away when i get into bed. i see the flashing lights and see pictures sometimes. Twise i've had the explosion sound happen, i didn't like it. What can you tell me about this Hypnologic imagery and what should i do with this stage? Where do i go from there?
