man, have i had a few! all of the experiences i've had have been witnessed by more than one other person at the same time.
i have witnessed full body shadow people not just ones lurking around or darting across my peripheral vision, but interactive shadow people who responded to voice commands as well physical interaction, like watching what we were doing, or playing along with us. they have also been in more than one location, mostly in residences/homes. i have heard disembodied voices, some just speaking out to no one in particular and some responding to direct questions. i have seen a full bodied aparition of a little girl, about 4 years old, she was in a bright white dress with lace trim a lot like a first communion or flower girl dress, ruffled white socks and white shoes, she had straight brown hair that was curly at the ends and was just past her shoulders held back with a white hairband, her clothing seemed to be from another period, but i just couldn't place an approximate date to it...she stood watching me as i sat on a friends couch watching t.v. early one sunday morning...this one i was alone for, but when i told my friend about her, he knew about her and pointed to the exact spot where she watched me from, he even described her movements/reactions, like how she stood holding her hands in front of her and kind of twisting from side to side like little kids do, which i didn't even describe to him. the girl and i looked at each other for what seemed like an eternity but had to have only been a few seconds...when i said hello to her, she turned and ran off in a playful way...i could hear the hard leather soles of her shoes slap on the hardwood flooring, then the kitchen linoleum, then stopping altogether...take to mind, this was not a very large house, and there was no carpeting, only wood and linoleum...i did get up to see if she was in another area of the house, but all i found was my sleeping friends. when his parents came home from church, my friend said "he saw her", to wich both his mom and dad replied "oh, you saw the little girl that stands here and watches you on the couch?", i was blown away...well, that's just some of it...i have lots more...i'll post some others another time
