Kinky practices with an individual who might get you dreaming (7)
I believe the answer is:
sandman
'individual who might get you dreaming' is the definition.
(fictional figure said to induce sleep)
'kinky practices with an' is the wordplay.
'kinky practices' becomes 'sandm' (S and M - sadomasochism).
'with' means one lot of letters go next to another.
'sandm'+'an'='SANDMAN'
(Other definitions for sandman that I've seen before include "Imaginary person who causes children to sleep" , "Sender to sleep of children" , "sleep-inducing agent" , "Children's bedtime fairy" , "He comes to send children off" .)
