Hello @yaziris,
You give the sense of a dizzying plummet into the insubstantial realm of the subconscious. There is a body of literature that deals with this phenomenon. This sort of literature expresses a sense of existential insecurity. The questions arise, Is this real? Am I dreaming. Which part of my perception is 'real' and which part is a chimera, a product of my imagination?

Not only does the sensation you feel when writing the story lead to a sense of dis-ease, but it evokes that sense in the reader. The one challenge you have when writing such a story is to help the reader keep track of the threads as you enter and descend into different dream states. You have to convey your sense of disorientation without disorienting the reader.

Mostly, you achieve that. The separation of parts helps a lot.

I think this was brave of you to write. It's not a classic adventure story, or romance. It is profoundly psychological. And I see no hidden pathology here. The same issue has concerned great writers across the centuries. If you want, I can give you a list :))

Great first try. Looking forward to reading more from you.
