"Did you ever encounter any psychotics in your practice that entertained
delusions and fears about "outer monstrosities" that they felt threatened
them? ... "
No, never had Kenneth Grant knock at the door, heheh. Seriously tho, I'm
afraid not. You get everything imaginable, but it tends to be drawn in broad
strokes. Many patients describe bizarre and frightening hallucinations
without the least suggestion of fear while some will speak of nebulous
wraiths and shadow figures that scare them witless for no real reason.
Psychosis is more emotionally invested in the message than the image.
Speaking clinically, severe forms of psychosis tend to focus around primal
collective concepts, such as God, the government, sex and the internet. Most
supernatural ideas in psychosis stem from popular religion, so here in the
U.K., anything nasty tends to have a Christian motif. I used to meet
patients who were regurgitating the Dennis Wheatley novels that seem to
breed in psychiatric hospitals, which suggests your query would be entirely
possible if Lovecraft was as popular as he is respected.
The closest thing I can offer - and I'm tight on the details because it's my
own frustrated writer's pipe-dream - is that when my old hospital was
closing down, I spent about six months as the night shift manager of an
empty asylum. Everyone else was too superstitious to touch the job, calling
up murders and spectres they'd have given the patients pills for, so I just
couldn't turn it down. Nights of miles of run down wards, basements, medical
units, mortuaries etc... in perfect silence and often via torch-light. Truth
is, it was mostly dull, so I'd entertain myself by remembering the weird
things I'd heard and scaring the crap out myself... then I'd have to move
the furniture so that the next time I came by I'd know it was me who did it.
Some of the wards were so symmetrical I could walk in and picture my
doppelganger opening the door at the far end. What I realised was that a
building of such size and reputation has a personality. Nothing supernatural
but quite distinct. The closest thing I've found in fiction is a short story
called "All Hallows" by Walter De La Mare. Well worth an hour's read.
As for George Zucco, sounds to me like he was a victim of Kenneth Anger's
high camp rather than Lovecraft's Mythos. Given the choice, I'd be a
Norwegian sailor.
"There might be something more sinister going on. Look, we've got Pugmire
with his Lovecraft monomania, Arthur B. with his tight-lipped newsgroup
lurking, Ramsey with his bouts of depression that may be the source of his
creativity. All that strangeness is going on right here at this
newsgroup--don't you think mind-probes from Cthulhu may play a role? I just
don't know..."
I'm just a friendly guy who's pleased to finally join the conversation. No
way am I Nyarlathotep. ;-)
