Hey all, wasnt sure where to post this but... Lately i have been hearing some strange things, the first thing i heard was someone hawking a lugee and spitting it, and it sounded like it was right next to me, but when i looked around, nobody was there. Tonight i heard 2 things, one i was listening to music and suddenly i heard a man yelling and i pulled my ear buds out as fast as i could and listened to see if i could hear it again. And just now i heard a knock on my door but nothing was there. I have a pretty stressful life, and sleeping is a huge problem untill 7am then i crash. Is hearing things normal? And if not, What do i do?
