I hallucinated gnomes after I took medicine they prescribed me at the hospital, following a bike accident.

Yeah it used to be common advice to not take any drink, food, or medicine prescribed by gnomes.

I need to learn how to construct sentences better :(

That may have been a bad reaction. Ask your doctor is KDE is right for you!

I switched to xfce since, much better

Sounds like you may have been hallucinating to begin with.
