Do you believe in Spirts and have you ever done an EVP?

I have been having strange things happen in my new apt for sometime' and last night i put a digital recorder and said to talk into it and some other stuff' and last night when i played it back you can hear a low voice saying i'm here.It freaked me the hell out but it's exciting all the same' as i have lost 20 or more to death...I am not a kook or crazy as spirits do exist in many places on earth.
