I think people are definitely curious about things we don't know or understand. It's the unknown, uncharted territory. It can be exciting and scary at the same time.
Maybe its because I always stay up waaaaay too late, or maybe because I have an overactive imagination, who knows. Maybe i'm just too caught up in what 'could be' or what might be 'out there'. Maybe I'm just sleepy and rambling about nothing, lol!
