I had a dream that I was at a party and I got drugged and I tried to walk home alone and got lost I see my that all kinds of people where out searching for me yelling my name but walking right past me and they couldn't see me. In the dream I coundnt move I couldn't talk. It was winter and u was freezing to death in a bank of snow and no one could find me. In my dream I was about 17. In real life I'm 23.
