The word from the Old English for 'joy' associated with sleep is 'Dream.' Human sleep patterns are diurnal, while many animals are nocturnal. Dreaming typically occurs during the REM stage of sleep.
Step-by-step explanation:
The question is asking for the word that comes from the Old English for 'joy' and is associated with the act of lying down to rest. The correct answer from the options provided is D) Dream. This word is historically linked to joy and is related to the experience of images, ideas, emotions, and sensations occurring involuntarily in the mind during certain stages of sleep. It is important to note that the context given in the question combines the concepts of sleep and joy.
To understand the concept further, it's beneficial to reflect on various sleeping patterns. For instance, human sleep patterns are generally diurnal, meaning we are active during the day and sleep at night, while many animals, such as nocturnal species, have the opposite pattern. This indicates the diverse nature of sleep across different species, but dreaming, when it occurs, is typically associated with the REM stage of sleep, which can happen whether an animal sleeps during the day or night.
