I'm not sure, the logical part of my brain tells me that I shouldn't, but part of me thinks it is possible. I mean there are a couple of things that make me want to believe.
I have mentioned before that I work as an undertaker and often I have to go out at night to collect someone who has died in a nursing home or their own home. This involves me going to to where I work to collect the car that we use to transport the deceased. I'm not saying it happens every time, but every now and then I get the overwhelming feeling that I am being watched by something and often that it doesn't want me there.
Now this could be my mind reacting to the where I am at a late hour, but whatever it is, needless to say, I don't hang around for too long.
Another time, about 10 years ago I was working in a bar, it had got to that point on a Sunday where everyone had gone home and I had cleaned up and was waiting for the arsehole that was my manager to turn up and lock the place up. So I'm just kinda chilling out on the sofas, but I can't see the door and all of a sudden I hear someone walking across the wooden floor towards the bar, I get up to see if its a customer or at least my manager turned up early for once. There is no one there, I look around the place check the toilets if someone has gone in there. No one. That was a fun wait for the dickhead manager.
