The answer is E. Dream.
Snore, slumber, and doze are all words that describe different stages of sleep. Snoring is a loud, continuous sound that is made when a person breathes during sleep. Slumber is a state of deep sleep, while doze is a state of light sleep. Dream is a mental experience that occurs during sleep.
Dreams are a series of images, thoughts, and emotions that occur involuntarily in the mind during certain stages of sleep. The content and function of dreams are not fully understood, but they have been the subject of much speculation and study. Dreams are often seen as a way for the mind to process emotions and experiences, and they can also be a source of creativity and inspiration.
In contrast to the other words, dream is not a state of sleep. It is a mental experience that occurs during sleep.
