I imagined too much of this kind of ghost, but I knew he isn’t real. But one day some weird things in my house were going on:
-Some of my lamps went on/off
-Some of my things moved from one place to another
-I feel warm and cold spots everywhere in different
areas in my room
-I hear some strange [...]
i can talk and see a ghost. her name is marry and she is 15 but i don’t know what to do can you help me?
I watch ghost hunters all the time and they come up with ghosts a lot but im not sure if they are faking it or if it’s real?
