I think I would do something similar -- get out if things were dangerous but then try to see what was going on and if it could be stopped. If nothing would stop it, I can't imagine leaving my family in a position of possibly being harmed -- no matter if it were human or spirit (or demon!). We'd have to leave -- and hope it didn't follow us! I've always wondered though -- could I (morally) sell a house, knowing something was lurking there, without telling the buyer?!

I think Mark would believe me -- or, at the very least, believe that something was happening -- even if it wasn't ghostly. I'm not necessarily a calm character all the time but, unless I had suddenly become delusional, he knows I wouldn't make up anything like that. Not sure if my kids would believe me or not -- they probably would but, honestly, I don't know if they believe in the supernatural or not -- Carrie likes the ghost shows, too, so she'd probably come the closest to believing -- but then again, she's another me!

By the way, most of the ghost shows don't frighten me at all but there's one called "Paranormal Witness" (on SyFy, I think)  that actually gives me the creeps sometimes -- and it's weird because they seldom show any evidence, they just have the people talking about what they experienced.
