First, pick a feeling. This could be as vague and easy as anger~sadness~excitement~fear, or as nuanced as contentment... etc.
Then go through your senses and find words and concepts that remind you of that feeling. ie, Anger:
-FEEL the beating heart and heat in face and blood, the sweaty palms
-HEAR a ringing in your ears, or a shout you make
-SEE your vision become tunnely and closed off, or your face go read
-TASTE metallic in your mouth, or blood, or a food that reminds you of a time you were angry
etcetera.
Now, think of words that'll describe those senses. A beating heart is POUNDING and DEAFENING...
The feeling is your MOOD, establish this first ("I was angry"). Then use the descriptive WORDS to describe the SENSES.
