Place it at the very start of a wake-up or time-reversal edit, before any dialogue, then follow it with a funny ha ha laugh when the character realises the day is backwards, and finish with an air horn club sample for the reveal.
About this sound
This clip takes the familiar Samsung phone alarm and plays it backwards, turning its rising chimes into a strange descending pattern that still feels instantly recognisable. It sounds oddly dreamlike and unsettling, like a morning alarm heard in a mirror, and it makes a normal wake-up feel funny and slightly wrong.
