I' ve been freeked out a few times while walking threw the woods in the dark. It' s funny, you hear something running and you stop and try and figure out if it' s going away or comming at you. Also, sometimes your imagination can start to wander and get the best of you. Stop and tell yourself to chill out ya big baby! Everything out there is afraid of you.
The reason your not bothered in the morning is because your too damn tired to care.
