Your dream reminded me of the movie 'Saw', especially when you said someone was watching you. I found the memory palace thing very interesting, in fact it was inspiring for me and I see it was for you too.
The drawing and details are spectacular, you are very dedicated and talented. I like this kind of fantastic art where all the ideas conjure up a story on paper. Your vision has impressed me, never lose those strange dreams.
Oh, I have seen 'Saw' ages ago, but fortunately my dreams are more surreal, rather than gore - for which I am thankful :)
I am glad you like my piece:)
See you around!
