Does my crush like me or am I just imagining it?

We are both 22. I met her this semester at class, so we haven't known each other that long, but after a few months interacting with each other I completely fell in love with her. Im pretty shy when it comes to this type of stuff so I've never told anyone and I don't think she knows I like her. I should add we're good friends, so I may be mistaking some signals, I first started suspecting that she might like me when she started being playful and touchy with me, she would jokingly pull on my hair (its kind of long), tapping my head or poking my ribs, when someone showed me something on their phone while she was behind me she leaned forward so she could see the phone as well and she rested the front of her body on my back and shoulder (Also she doesn't seem to me to be a touchy person, she's kind of serious and often quiet with people she doesn't know that well). She also says what I think were kind of flirty comments, the strongest of them being one time when talking about movies I said "I like characters that are neutral" and she responded with "Well I am neutral" which if it was a joke then I can't figure what she meant by that. Am I just trying to convince myself that she likes me? Am I misreading something? or is there a chance?
