It may be some kind of negative/prankster entity messing with my head, I've noticed a lot of interference with electronic devices..and other strange occurrences..and I've felt it's presence only at night when its near bedtime. Whatever it is, it hides itself very well and seems to affect people around me as well, it changes their mood toward me. It seems to follow me everywhere. Could this possibly be some kind of ET entity?

Could it be possible of some kind of ethereal/physical implant? If so how do you remove them?
