I’m into stories showing the inner self (5)
I believe the answer is:
anima
'the inner self' is the definition.
(I've seen this in another clue)
'i'm into stories' is the wordplay.
'into' means one lot of letters goes inside another.
'stories' becomes 'ana' (archaic term for anecdotes or gossip).
'im' going inside 'ana' is 'ANIMA'.
'showing' is the link.
(Other definitions for anima that I've seen before include "Part of psyche directed inwards" , "Inward part of the psyche" , "Showing true inner self" , "Witty remark" , "Subconscious part of the psyche" .)
