Seeing People And Objects That Aren't Physically There

This story begins a couple of weeks ago.

I was sitting in on my bed playing my guitar, when out of the corner of my eye I saw something walking towards me, It looked to be human, I looked and nothing was there, so I continued to play, as I put down the guitar, in the same spot as I was turning my head I saw it again, I quickly turned my head back to see nothing yet again.

The next day at work I was doing my usual checks, when I turned my head to see the same human out of the corner of my eye, I quickly lose my breathe and gasp as I look there is nothing there. At this point I'm thinking, "am I crazy"? Lately I've been using techniques to cleanse my Pineal Gland, to include sleeping with a high powered magnet on my forehead.

Lastly this morning I was in the shower when I saw through the glass a figure like a dog, I open the door to see nothing, of course I close it again, to see if maybe it was the lighting, and I saw nothing.

I'm thinking that maybe it has something to do with me de-calcifying my Pineal Gland, and I'm not scared, just curious if this is a effect that will take place because of my cleansing. It would be nice to have a little bit longer that a split second with these spirits, or beings.

Does anyone out there have any advice or suggestions with this type of vision. This is the first time anything like this has ever happened, I don't feel threatened in any way, so cleansing my house is not on my to-do- list, but I think a good musical talking to always seems to draw out something in my house.
