Past 2 night I have woken up at 3:15 and 2:50 and I couldnt get back to sleep for about 2 hours. Ive heard stuff about paranormal activity and Sugar but that seems pretty fake. Would there be any other reasons?
Possibly a noise outside disturned you/ You wouldn't registerr the noise conciously, but it could be enough to wake you - something like a car door slamming or a dog barking.
I really wouldn;t worry about it - unless you have something specific on your mind which needs to be addressed - that will solve the problem.
to be brutally honest I can't think of anyone who'd assume paranormal activity was involved for something so mundane as not being able to go back to sleep!
