Wo! chamaeleon! bet you glad you moved!
im constantly seeing things around the house out of the corner of my eye, like black shadows but its allways low down like on the floor , only thing i could attribute it to is an old cat of mine that died, my sister claims to have seen "back legs and a tail" fly round doors or up the stairs ect!, strange! doesn't bother me tho! My friend once told me a story about how him and his friends where leaving the house to play football (or soccer to my american peeps!) and had excited the house except his friend who stayed in the kitchen to pinch a buiscut! he says he saw a shadow out the corner of his eye who told him to "leave it!" in an angry voice, he went outside to join his freinds and he apoligised about the buiscut , and they didnt know a thing about it. no one else was in the house!
maybe its all residual energys that are floating about, who knows!
