I remember seeing a glowing round blue/greenish small object hovering in my room by the door as soon as i tried to get near it, it would vanish i saw it at least twice. I believe there is always a presence or someone with me. Maybe thats just me, either way its creepy. The second time, it was early this year at night, i was laying on my bed and saw my sister's shadow walk in i assumed it was her, no big deal and i just started talking and talking but she didn't say anything i sat up and nobody was there i know i saw somebody walk in but apparently it wasn't her. and of course i have heard footsteps..
