Folk commit to living in virtual bubble — all may introduce this recollection (6)
I believe the answer is:
memory
'this recollection' is the definition.
(I've seen this in another clue)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for memory that I've seen before include "Computer storage" , "Mental retention" , "reminiscences" , "The ability to store things in mind, and to recall (6)" , "Power of recall" .)
