So...Confused.

I have a boyfriend. But, I keep thinking about this guy who I went to school with. I moved last month, but I can't stop thinking about this guy. I have no idea if this is normal. I only had like two classes with this guy! So I'm just confused. And like, I had a weird dream about him last night. so I'm slightly confused and slightly afraid to sleep incase I have that dream again. Help?.. I just want to know if it's normal. I tình yêu my boyfriend to death. I'd die for him if it came down to it.
but this one guy I just can't stop thinking about...AHHH! HE WONT GET OUT OF MY THOUGHTS!!!!
