Answer:
Stage 1.
Step-by-step explanation:
The stage of sleep characterized by small and irregular brain waves, a sense of drifting out of consciousness, and recalling visual images is Stage. This is a transitional phase between wakefulness and sleep, often associated with a feeling of falling. If you awaken someone during this stage, they might report that they were not asleep. The brain is still relatively active and producing high amplitude theta waves, which are slow brainwaves occurring primarily in the brain’s frontal lobe. This brief period of sleep lasts for around five to 10 minutes.
The answer is Stage 1. This stage of sleep is characterized by small and irregular brain waves, a sense of drifting out of consciousness, and recalling visual images.
