“One of my direct manifested encounters was surrounding my participation in the game Dungeons and Dragons back in the 80’s along with the music I listened to at the time”
Sure.
“A being attacked me in the night from which it was surrounding my pile of books, maps, notes and albums”
Who keeps their music with their D&D books?
And you forgot dice. REAL D&D players always had their dice in the pile.
Our connection to our dice was mystical. Music, not so much.
“in which it made loud, clear and definable noises.”
Definable? That means you could tell people if it was meowing or barking?
Do you mean something else? Definite noises? Detectible noises?
“Once I approached, it physically came up against me but the Holy Spirit ushered it away so that it may not posses me.”
Why?
If you had so much D&D crap that you summoned demons by critical mass, why was the HOly Spirit even in your place?
"My friends had similar encounters, I thus got rid of that stuff.”
Uh huh. I started playing in 1980 at a training command with a couple dozen gamers in and out of each evening. One, exactly one of our players had a reality infarction and turned himself in to medical when his character got an STD. That must have been a fun interview. “Do you know who you got it from?”
“Yes.”
“Can you describe her? Where this happened?”
“Well, there’s this tavern on the southside, and this blonde half-elf saw me spending gold…”
“Did you say….half? Elf?”
“Much happened in those days and not all were as guarded as I, it seems.”
So, wait, there’s a demon that shows up where your demonic rulebook is, but can’t ‘get’ you because Gawd. But other people had the same books, and made the same summoning, and weren’t protected AND THEN TOLD YOU?
Does this actually make sense? Would you like to start again?
