If it was an evil spirit, he/she/it would drive you to the point of getting you sick or mad (crazy mad, not angry mad). So when the evil spirit is talking to you, you're not using any technological devices? That's cool, but if a spirit manages to communicate to you like that, then I assume it has a lot of energy! Despite being a believer in the paranormal, I'm no expert XP

There are some spirits that linger in people's houses then go away. For instance, there was a time where a male voice literally shook my room with his laughter (3 laughs). I freaked out and never slept in that room again because two other incidents happened to me in my room. In conclusion, some ghosts, to me, like to prank or people's strings just to get them scared, but if it's really messing you up and it continues to get worse (like physical harm), seek a psychic or cleansers, or try simple remedies that you can use to cleanse your room!
