Plans made by pub, uneasy feelings being picked up (10)
I believe the answer is:
intentions
'plans' is the definition.
The answer and definition can be both related to thinking as well as being plural nouns.
Perhaps there's an association between them I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for intentions that I've seen before include "The goal with respect to a marriage proposal?" , "Aims" .)
