Just a glimpse of a dream I had last night.
The man is Giovanni J. Johannes, a veteran Imperial Officer (Star Wars universe) who is recovering from a really bad injury that left him somehow brain damaged and with huge mental health problems.
I clearly remember this man struggling every night to regain control of his subconscious, having some weird nocturnal meeting with his hidden alternate personalities into his mind palace. The first one (who appeared on the first night) was the most fragile one, probably the true personality of the Imperial veteran.
The second one appeared on the second night and abruptly absorbed the first and - there I was about to scream in horror - even the physical manifestation of the man. Then, when the morning came, I knew the kind and fragile man who was J had ceased to exist, his conscience being replaced by the twisted personality of the previous night.
Then I woke up.
The drawing is referring to a particular moment in the first night, during the transition to the mind palace, when he faced his damaged conscience for the first time.
(The J stands for Jeremy, as the man was essentially the late actor Jeremy Brett)
EDIT: I added a blurred background to make an example of the mind palace style (pretty much like a Witch Barrier from Madoka Magica)
