I believe something is out there, I believe they are spirits but Holy ones, I believe that the unknown is what we should not fear and believe that just because something is invisible does not mean it isn't in existence.
I truly believe in God (the almighty creator and he controls all that live and die)
However I do not believe that the dead (our passed loved ones) walk the earth with messages. I do not believe you can directly speak to the dead for the living.
Evil spirits also exist however they are only evil if we allow them to be. Any spirit feeds on our existence.
