actually I think it's fucking awesome that you had a dream of a sub. this happened to me only once but I didn't try it out so it went to waste and I forgot about it. Dude don't listen to the haters that's really fucking cool that you saw a sub in your dreams.
remember when you dream your brain releases hallucinogenic chemicals. dreams are when your brain is in it's most creative state, unless you are meditating or on some kind of mind altering substance. sometimes I hear music when I dream, sometimes I see really crazy shit, like a salvador dali painting.
try the move out dude. Idk why there are so many people hating on the fact that you saw a new sub in a dream. I think it's really fucking awesome.
