A couple of comments

The language barrier is a bit odd and out of place, if someone has the power/ability to physically turn you into something else, editing your brain to make sense of the new senses, rewriting your instincts, changing your proprioception etc. It would stand to reason that they would throw in a free language change while they were at it.

It isn't until the fourth chapter that you mention what you've been turned into and even then it's super sparse in details.


an SCP blend is kinda interesting, but announcing yourself as being an inter-dimensional being is extremely unintelligent.
No hard proof, reasonable government response = loony bin
SCP organization exists = Locked up forever, or just killed.

Also ranting about how it is /isn't reality = loony bin


Your character seems to have a severe difficulties in planning or thinking things through to their obvious conclusions.
