Tick tock RC

Hi, sometimes when wilding, i am unsure if i am in a false awakening or not. Im reluctant to perform a physical reality check in case im awake and mental checks are not too reliable. I do have a clock next to me all night going tick tock tick tock. Can this be used to determine if i am in a false awakening in some way? I have tried in the past and heard the tick tocking and so assumed i was still awake. Is it likely that is i was in a false awakening then i wouldnt hear the ticking of the clock or maybe hear a distorted version?
Thoughts please guys :-)
