In some cases they were definitely not things they had lived before they arrived here. Or at least that's what I understand.
And, I'd want to say psychic's don't exist. At least, I've never seen any proof, back home anyway. But, I highly suspect that in this place I could be found to be very mistaken.
However, I've dealt with a lot of brainwashing and similar things recently. And, I just want to take precautions.
