Flash O' Fire


Last night as I got into bed I thought I saw a flash of fire across the room. I didn't, of course, but thought I did. This happened twice. One of the things is that our our eyes only see bits of what we actually see, and our brains fill in the rest, so it's no wonder that that we get optical illusions and hallucinations.

This is probably the reason why people see ghosts, apparitions and UFOs and aliens, sometimes you see what you want to see rather than what is actually there. I often see things which I know cannot logically exist where I see them. It's always and instantaneous thing, that I see for a split second, though I am not sure what I would do if the apparition became persistent to the point of me believing that it was actually real, but some people are less fussy.

Another optical effect I've come across is that way objects that are further away seem nearer the further away from them you are when you view them though a window. It is a real mind bender when you first notice it and even when it is explained to you, which makes perfect sense, your mind still rails against the actual effect. Here is my Instagram post about it. Here is the Sydney Opera House Illusion explained.

Again this gets me to those 3D Magic Eye drawing images which  were big in th e1980s, though most of the time I really couldn't be bothered to concentrate to see the images. Then we go to th emind bending art of MC Escher which again bend reality for you and did inspire a scene in "Labyrinth" which bring David Bowie into play for this post.
