Please Help Me!!!!! Do I still like him? Is it sad that I still think about him? Do you think I messed up our friendship?

So there is this guyand I used to like him a few years back and we go to the same school and whenever we pass each other in the halls it is really awkward because I'm either looking at him or he is looking at me. School is out now and now and its just weird because I think about him maybe like once or twice a day but in like a friendly way.Then yesterday I had a dream about him and we were almost like best friends like we were years ago.Then last night I had a dream about us like dating and it was really weird for me because we were sleeping together in the same bed. Please Help Mep!!!!!
