Such stuff as dreams are made on
Now things got even more extraordinary. I began to see very vivid hallucinations.
I’ll try to describe them in another post: for now I’ll just show you some I was able to sketch before they flew away.
I saw them all so often I gave them names, as follows:
A the Hexagons
B me jumping into a vortex
C the Pennants
D the Gingerbread Man
E the Bubbles
F triangles
G the Chequered Tablecloth
H the Scroll
I Benzene Rings
J Herrings and Undulations
K the Hand
And this was just the start, they morphed, as I’ll try to describer in the next post.

Ah! I have just read a book called Hallucinations by Oliver Sachs and he talks about just this experience when vision is incomplete or missing. There is even a name for it (which I can’t remember!)
Oh I didn’t know. I admire Oliver Sachs, I must get the book, thanks!
