“We were on the track ahead as the nightmare plastic column of foetid black iridescence oozed tightly onward through its fifteen-foot sinus; gathering unholy speed and driving before it a spiral, re-thickening cloud of the pallid abyss-vapour. It was a terrible, indescribable thing vaster than any subway train—a shapeless congeries of protoplasmic bubbles, faintly self-luminous, and with myriads of temporary eyes forming and unforming as pustules of greenish light all over the tunnel-filling front that bore down upon us, crushing the frantic penguins and slithering over the glistening floor that it and its kind had swept so evilly free of all litter.” (H.P. Lovecraft - At the Mountains of Madness, 1931)

Read a lot of his stuff as a teenager in the late 60’s early 70’s..........
When I was 8 I fell and broke my arm, the doctors
were incompetent and they had to break it and reset
it 5 times. Ether was in use at that time and lovecrafts
description is almost exactly what I saw EACH TIME.
They finally had to hold me down to put the mask on.
My parents finally woke up and took me to a specialist.
He cut the cast off manipulated my arm, put a new
cast on and I’ve been good as new ever since.
Honestly, it looked like a glowing brain with eyes
set all around it, filling the cavern and persuing
me until I reached a dead end at which time I blacked
out. Can see it today.
