evp is when you catch supposedly "voices from the other side" there has been so many cases. some can be written of as background noise or interfereance i suppose but when the investigators actually get direct answers to their questions, its not so easily written of. i tried it myself. i went to an area where a woman got killed near me. you record for 30 seconds then you start asking direrect questions. so i did, and the first few times i got nothing, then i got a lot of things in one night. at one point i had said, "say something, prove to me your here" and the was a kind of echoing woman's laugh. another time i had said "where are you" and i was answered with "i'm coming" it was rather eerier at first but i got used to it. its very interesting and hard to explain.
