i have two experiences one is when i was little my sister and I and some friends were playing a game in the basement. All of a sudden this transparent blue shining lady that was wearing a dress came out and said all of our names. I was scared shit-less all i could do was sit there and stare at it. My sister literally picked me up and shoved me through a small basement window.
Another time is at the apartment im living at now. My friend and I were playing Metal Gear Solid for psx in my sister's room. My sister wasn't home, but she said that we could play it in her room. We were sitting there playing for like 2 hours I think we got up to Raven because it was the first time we had played when from out of nowhere I heard a voice come from the closet that said my friends name. We both ran out of the room as fast as we could then as soon as we went back in the room we looked in the closet and there was nothing.
