YO.... What happened to him... I had the same experience omfg it was terrifying.... I too slept in a bunkbed(and at the top too) but the shadow person... instead of between the protection wall... it was standing really tall up and tilting towards me so we were almost head on head and... what really upsets me is that even though we were so up close towards each other I couldn't see nothing other than a shape of a person... no eye, no nose, no hair or clothes... Just a dark shadow... And since I was already lying down, I just gasped and covered myself on the covers like a kid lmao... I don't even know how much time passed until I could peek out but GOD It was scary.
Even now, a decade or so later I still don't know if it was someone on the house or not... :'(
