Dreams.....ex boyfriends....?

The night before I was sick from my stomach then ate some hot soup because I felt empty in my belly.Then I vomited later,but I bought jello to eat something since I didn't want to eat anything.Then I couldn't sleep,so I took some Nyquil to sleep better.I felt like I slept good.Then I had a dream that Freddy Krueger was in my dream,but I just saw him.He didn't do anything.Also I was walking down the hall at some school I never been to in my life and out of nowhere my ex boyfriend pops up to say hi to me.Then he keeps staring at me while were walking and he then grabs me and kisses me on the lips.I try to pull away,but I stay a few minutes and then I slap him.But when I leave someone yells hey let her go!I was like wtff..then I think to myself as I walk that I actually liked when he kissed me.What could this possibly mean?I say to myself I'm over him,but somehow idk...I saw him yesterday but I got the feeling he was staring at me a lot in the lunch room then I couldn't stop staring at him in the morning......odd.I cant get away from him cause we have the same friends,so somehow were going to see each other. :/// And its weird that if I don't acknowledge him and say hi to him he texts me out of the blue or messages me on my space to say hey how you been or tells me you never say hi to me,but I just reply well you do the same.I don't get him.I mean if he broke up with me why does he act odd around me and plus I don't talk to him anymore.He poked me yesterday and then left really fast while I was sitting down with friends...I was just like wtff?
