Pull in and seem to be under the influence (4)
I believe the answer is:
reel
'pull in' is the definition.
(thesaurus)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for reel that I've seen before include "Move unsteadily (like a Scottish dancer?)" , "long stretch of film" , "Lively dance; bobbin" , "Dance - swim" , "Totter" .)
