A "ghost" phased through my shins as a ball of light initially.
A "ghost" moved my parent's 500lbs sleigh bed several inches while sleep (you can see the carpet indentions; fitful sleep doesn't do that.)
A "ghost" appeared as a male apparition, staring my grandmother in her face at bed level, and my uncle came in and saw this same apparition after turning on the lights.
A "ghostly" present made even my cat fearful of going into a room, fighting my pushing over the threshold every time.
A "ghost" texted us when praying, calling my mom a female dog, only to find out the number never existed when we immediately called back.
A "ghost" scratched me while sleeping - in lucid dream - with the claw marks inverted (i.e. in no direction I could have scratched myself.)
And, there is so much more. Hollywood may sensationalize the spirit world, but that shouldn't suggest it is not real. I have been assaulted by these entities - ghosts, demons, whatever you want to call them. My family has traceable back many generations. They are deceptive, nefarious entities that work on deception...even if that deception is convincing people they do not exist.
Angels make themselves known; they do not go through hoops to mask their identity. And, often they appear as physical humans, not ethereal familiar spirits. This stuff sounds wacky until you experience it first hand. Then, you become the one crowned with a tin foil hat.
