Well, it would be nice to be able to prove it. I have ghost photos, and EVP's, but of course you would just argue them, so I am not going to post
them. I can tell you I started ouot as a complete skeptic. I didn't believe in ESP, or psychic phenomena, ghosts, god or santa clause.
Then I married a girl from a truly psychic family line, and very quickly I had come to believe in the psychic/esp side. Ghosts came soon after. You
have to admit there is something there when you sit and watch things move by themselves. You have to admit there is something there when you are
coming up to an intersection and you wife says STOP even though the light is green, and causes you to brake just enough to avoid a pickup truck that
comes out of nowhere going 70 miles an hour and blows the redlight. Even though she did not see the truck coming whatsoever, a voice whispered right
into her ear. Spirits that my wife doesn't even know come to her, sometimes trying to get messages across, sometimes I think just because she can see
and hear them.
I have seen spirits as real as life in a sweat lodge, and ghost lights or what people refer to as "orbs" are very common in a sweat lodge as well. I
tell you this. be happy your eyes are not opened, because it changes your whole life when you have to believe.
As for animal ghosts, they most certainly DO exist

We have Yorkies, little dogs, and they run in a little pack. Several have died over the years,
yet when the dogs all come running for treats or because someone comes to the door, sometimes there appears to be more dogs than we really have. The
others are still here.
We had a huge North American Timberwolf that went about 160 lbs. A truly big massive dog. He ate something that poisoned him, and died suddenly. He is
still here. He sometimes is at the end of the dirt road, and runs up the road with me. I just catch glimpses, but he's still here. When we sit in the
yard, he is there. One night he came slinking up on our bed and scared us to death in the middle of the night. That really freaked us out cuz he was
heavy and pushing down on the bed.
So hey, open your mind. Go seek out some spiritual guidance. Work with meditation and your chakras. This all helps you to connect. We all can do it,
so go seek it out like sonya said in the beginning.
