Blind spots
What goes on in this world that we can not see ?
Portals to other dimensions behind every tree or through the cracks in a wall. Just like the old movie trick to make it seem somone had disappeared through a wall.
If these do exist how can we learn to see them or to use them ?
Is it just a paranoid delusion thinking they might be there?
Do things change in front of your eyes in this world ?
Perhaps you could look at something and then after looking away it is different but your mind tells you that you are seeing the same thing or that things looked like that before. How would you know ?
Imagine being in a room with just a few other people and one of them disappears. You can not see whaere they have gone perhaps you just missed something, perahps they know something you don't and teleported to another place, perhaps they don't know they disappeared, maybe to them they just decided to walk somewhere and accidentaly teleported or used one of those hidden doorways and ended up exactly where they had in mind to go.
I guess I have a lot more to say on such things but finding the words is hard for me.
