Very good read, thanks for the post and please keep going when you have the chance.
Like many people said here, I also think it's not your typical "spirits". Powerful demons like this do exist and many of them are very capable of
physical threats.
Not to hi-jack but to enforce the believability of stories like this: my auntie's 1st born died due to a demon choking it. A few months before the
baby was born, she moves into an old room in her mother-in-laws home. She and her husband would wake up in the middle of the night with a bed that's
shaking violently, and at night when she comes down to make milk for the baby, she smells incredible food being cooked etc.
They moved out after the death of the 1st born and that room was sealed, now her 2nd and 3rd child are all in HS, very smart kids.
Sorry for the hi-jack, but please do continue!
