Occasional bits of false info in your dreams (2,2)
I believe the answer is:
as if
'in your dreams' is the definition.
(I've seen this in another clue)
'occasional bits of false info' is the wordplay.
'occasional bits of' indicates alternate letters (letters selected at regular intervals).
'false'+'info'='falseinfo'
The alternating letters of 'falseinfo' are 'AS-IF'.
(Other definitions for as if that I've seen before include "Or though" , "Seemingly" , "a voice of doubt" , "You're joking!" , "Yeah right!" .)
