I guess a group of people seeing or hearing the same thing is all in their heads? I'm not talking about at seperate times where one person says, Hey, I saw this.. and the next day another person thinks they saw the same thing.. I'm talking all at once...
Here's a few real life events that's happened in one house my cousins lived in..
When my little brother and our cousin were younger there was one bloody foot print starting below where the attic fan was that trailed all the way into the bedroom under the bed..It was a kids foot print so we thought it was one of the boys.. Neither one of them had cuts on their feet..
There's a hand print on the wall that won't go away, it's been painted over, the piece of sheetrock was removed and replaced and painted and it still showed up..
My daughter talks to something she says is a ghost... I took a picture of her once standing in the hallway while she said "it" was there and a shitload of Orbs showed up around her...
I'm just a nut though..
