My dream

The other night i had a dream, I was at my house in teh middle of winter and i was really scared. everyone went to bed and i looked out the window to see this girl that goes to my school. she was frozen with her eyes wide open. Last night i was at my dads house and at 12pm this guy from my school came and knocked at our door to use the phone. It creeped me out because nobody ever just randomly comes to our house to use the phone. any connections perhaps?
