A feeling it could be mine too (7)
I believe the answer is:
emotion
'a feeling' is the definition.
(emotion is a kind of feeling)
'it could be mine too' is the wordplay.
'it could be' indicates an anagram (I've seen this in other clues).
'mine'+'too'='minetoo'
'minetoo' with letters rearranged gives 'EMOTION'.
(Other definitions for emotion that I've seen before include "A strong instinctive feeling" , "Intuitive feeling" , "Fear possibly" , "Strong feeling as of love or hate" , "Surprise, perhaps" .)
