Dreamwhite

While walking through different levels of Dream Core, you came across some kind of portal and decided to enter it.
You were transported to some level, consisting of only one room, and in front of you was a door with a bunch of signs, and on each one something was written, on the first: "psychopaths, murderers and other representatives who can harm due to their psychological deviations, RESPECTFULLY REQUEST: DO NOT ATTEMPT TO ENTER"
on the second, just below the first: "adequate or simply harmless creatures: PLEASE KNOCK! I will open"
To the right of the door hung a third, with a picture crossed out with a red cross, which depicted a man and a climbing eye next to him
Below it was the fourth and last: "NO ENTRY FOR BAT OR Erect EYES! (I do not let such people in, just to be on the safe side...)"

You decided to knock.

Which you definitely didn't expect
You heard someone's disgruntled grumbling from inside

• But it says on the door, "Knock and I'll open the door"!! Why does everyone always have to knock down my door?!

A young man appeared from the darkness.
(Dreamwhite is a scientist mechanic who used to work in a team, but now lives alone, black disheveled hair with a hairpin in the shape of an eye, large glasses specially for work, a black bandana covering his mouth, a long medical robe with patterns in the form of yellow lightning in some places looks shabby, a striped shirt of purple and dark purple, a white jabot, black pants, yellow boots)
Noticing you, he looked gloomily at the door, then back

It was clear from your appearance that you yourself were in shock from the door falling, and you hastened to justify yourself:
