If you are friends with someone but never thought of them more than that but then one night you had a dream you were kissing what does this mean?

Dreams are complicated-your brain can think of a whole bunch of whacky things in the middle of the night. If you still feel that you do not like the guy/girl then don't worry about it...this stuff happens all the time. But if you feel more attracted to them now...then maybe your subconscious was trying to tell you something. In which case---go for it!
