Activate mind-blowing experience (4)
I believe the answer is:
trip
This clue could be a double definition.
'activate' is the first definition.
(I know that activate can be written as trip)
'mind-blowing experience' is the second definition.
'trip' can be an answer for 'experience' (I have seen 'Hallucinatory experience' mean 'trip' so perhaps 'experience' could also mean 'trip'). I am unsure of the 'mind-blowing' bit.
Can you help me to learn more?
(Other definitions for trip that I've seen before include "In close confrontation" , "Device working a trap or alarm when stumbled over" , "Journey - miss one's footing" , "Run - dance - tumble" , "Excursion (while on drugs?)" .)
