Sleepy companion timid (7)
I believe the answer is:
bashful
I believe this clue is a double definition.
'sleepy companion' is the first definition.
(I've seen this in another clue)
'timid' is the second definition.
(similar in meaning)
(Other definitions for bashful that I've seen before include "Sleepy companion" , "Shy, timid" , "Neither Happy, Sneezy, Dopey, Grumpy, Sleepy nor Doc!" , "Doc's shy pal" , "One of Disney's dwarves" .)
