Feeling that may be common (5)
I believe the answer is:
sense
I believe this clue is a double definition.
'feeling' is the first definition.
(feeling can mean a sensation)
'may be common' is the second definition.
(I've seen this before)
'that' acts as a link.
(Other definitions for sense that I've seen before include "Be vaguely aware of" , "Eg, taste or touch" , "eg Vision, hearing" , "definition" , "Realistic attitude" .)
