What gives me the Heebeejeebees is being in a room with very large machines. Remember the cellar scenes in The Shining with the big boilers and heaters? YECH!
Also being underwater around shipwrecks. Double YECH!
Haunted's post reminded me of something that used to give me bad time heebie jeebies. Most homes in Texas don't have basements but I grew up in Chicago where homes do have basements. It used to scare me to death to have to go to the basement at night to get something. The stairs were open and I was always afraid that a boogymen was hiding behind the stairs and that he'd reach between the steps to grab my ankle.
Woodlouse - Andy calls them "slaters" - maybe that is Scottish for woodlouse. Up close they look sort of like little armadillos
I heard on the news today that little boy had what they thought was infection. They discovered it was a baby snail in his knee !! YIKERS
PS the boy has the snail named turbo.
