Sleep Confusion: Why You Might Question If You Were Asleep

It is possible to be in a state of confusion or disorientation when waking up and temporarily not know whether you were asleep or not. This can occur due to several factors, such as waking up during a deep sleep cycle, sleep inertia, certain sleep disorders, or external disturbances that disrupt the transition between sleep and wakefulness.

However, in general, a fully conscious person can usually distinguish between being asleep and awake.
