memorable

Ive been getting weird dreams of this girl that I can't even see her face at all & it started to scare me & this dream lasted for 2 weeks, then now this week I have been dreaming of my last ex that I really loved or still do & i don't know if these two dreams are the same, but the thing is her & I had a very good relationship & I was her first love & so she was mine as well. We lasted for a year & broke up for a stupid lie I made before we even dated.we didn't talk for a year & the only times we would talk were for our birthdays or just sometimes have a small chat to catch up. She is a grade lower then me & in two weeks I'll be seeing her every day when school starts. To think of it I'm probably having these dreams because ill be seeing her after a year. But still could these dreams mean something at all? Please help me understand, thank you
