Final answer:
REM sleep is the stage of sleep during which one will likely experience the most vivid dreaming.
Step-by-step explanation:
The stage of sleep during which one will likely experience the most vivid dreaming is REM (Rapid Eye Movement) sleep.
During REM sleep, our brain activity increases, and it is the stage when we experience the most intense and memorable dreams. It is characterized by rapid eye movements, increased heart rate, and paralysis of the major voluntary muscles.
For example, if you have ever woken up and vividly remembered a dream, it is likely that you were in the REM sleep stage.
