A few years ago, I had an encounter with a presence. I was home alone with just the cat. Sitting downstairs watching TV with the cat on my lap when I heard what sounded like a dog barking upstairs, but didn't own a dog. I just thought I was hearing things, until the cat starting hissing. I was about to go upstairs to see if somehow a dog did manage to get in when I heard it start coming down the stairs. I went for the pellet gun. Then I heard a growling coming from just a few feet away. The cat was going crazy, but there was no dog there.
What I saw was a dark shadow in the centre of the room. At first I was afraid, but then I thought "the hell with it", and told it to go away. It did. I never felt the presence again. Had the cat not reacted the way she did, I would have just assumed it was my imagination. I had never used a Ouija board and stayed away from anything occult related until that encounter.
I discussed this with a spiritualist who told me that the "being" was a manifestation of the negative aspects in my life. When I asked about the cat, she told me that cats are believed to have the ability to see into the spirit world and they will react to spiritual energies. I "defeated" the negative energies by telling the being to leave. After the encounter, I found myself becoming more open minded towards the spiritual side of our world. Things like the Ouija board and Tarot deck can be of great benefit to a person who uses them correctly. They are not evil. They cannot summon demons.
