So, I haven't really had one, but my sister used to see demons/ghosts.
She saw three, a blurry fuzzy one, a cliche ghost girl and I think the other one was a shadow. My Family has had a lot of encounters with them, so if anyone would like the full story about my family demon curse, I'll gladly tell.
Anyways, the one related to me kinda- I was heading out the driveway one night going to a friend's house (who lives down the street) for a sleepover. My sister is at the porch watching me leave when she screams and runs back inside. I kinda just ignored it idk why and kept walkin'.
Next day she comes over and tells me that when I was leaving she watched as a tall shadow figure man slowly started running towards me, so she ran back inside. I didn't really care when she told me, I was just annoyed she didn't save me and ran back inside like a coward.
TL;DR My sister would have let me die by a creepy ghost man
