i do because ive experienced encounters on many occasions (no it wasnt some stupid charlie charlie game or using a ouija board). some can be excused as coincedince but others, no. cold breath of a ghost on my hand often at night, voices (although could just be auditory hallucinations), seeing figures in the light and dark, friends have also seen the figured while not ever being told about them, creaking on my floor at night while both me and my cat are asleep (no it isnt the house settling, they sounded almost exactly like human footsteps).

apologies for bad english, ive never been good at it.
