Time perception can be distorted, though, and experiments show that estimates are generally good, but people tend to overestimate time passed during the early hours of sleep and underestimate during the later hours.
How does sleep affect sensation and perception?
Most sensory stimuli do not reach conscious perception during sleep. It has been thought that the thalamus prevents the relay of sensory information to cortex during sleep, but the consequences for cortical responses to sensory signals in this physiological state remain unclear.
Are you unconscious while sleeping?
In other words, a sleeping person is unconscious to most things happening in the environment. The biggest difference between someone who is asleep and someone who has fainted or gone into a coma is the fact that a sleeping person can be aroused if the stimulus is strong enough.

What happens to your perception when you sleep?
15 Ranks: You remain alert to sounds even in your sleep, and the normal DC increase to Perception checks when you are sleeping doesn’t apply to you. The distance modifier on the DC of your Perception checks is reduced to +1 per 40 feet. 20 Ranks: You gain a +10 bonus on Perception checks to notice invisible creatures or objects.
What happens to DC of perception checks when you sleep?
5 Ranks: You remain alert to sounds even in your sleep, and the normal DC increase to Perception checks when you are sleeping is halved. The distance modifier on the DC of Perception checks you attempt is reduced to +1 per 20 feet. 10 Ranks: The distance modifier on the DC of Perception checks you attempt is reduced to +1 per 30 feet.
When does speech awaken a sleeper from sleep?
Speech at a normal volume awakens a sleeper if the environment is otherwise silent (no wind, birdsong, crickets, street sounds, or the like) and the sleeper has a passive Wisdom (Perception) score of 15 or higher.
