fühlen, sich fühlen, sich anfühlen

First, a quick overview over what you need:

 fühlen

Expresses “what you feel”. This is the one you’ll need the least because usually spüren is more idiomatic for these contexts.

sich fühlen

Talks about “how you feel”.
If you want to say that you feel like doing something then Lust haben or Bock haben are more idiomatic.
If you talk about that you have an inkling of something you’d use “das Gefühl haben”.
And if you talk about opinion (feel about), then go with denken.

sich anfühlen wie

Talks about “how something feels” in the sense of “which sensations does it evoke”.
The solutions are at the end of the quizz and also, I’ll show them as audio.
Viel Spaß :)
