I Have a Ghost and I'm a Part-Time Roommate and I Feel Like I Have a Ghost

I've had lots of traumatic events unfortunately but I thought I would share something kind of fun so anyway I have lived in this house for about a decade and I have felt like it has a ghost but that ghost doesn't really live here full-time. It comes and goes sometimes I feel it's present and then there will be like large gaps of time then it comes back and something will happen  like a door will open or close or you know I'll feel like a presence but it's never scary it just sort of comes and goes, she says.
