reminds me how my mom told me that she had a dream when she was at her uncle's house for a night and usually everyone says "yeah its haunted as stuff" but they slept at it anyways
that night she had a very fuzzy dream of seeing people chanting downstairs and writing something out on the wall in some sort of red liquid; probably blood, and when she woke up
she told them that and they just laughed at how rediculous it was
like 6 years later they peel the wallpaper back for a replacement and they find some dark red writings on the walls and a pentagram
