Please choose the correct ending to complete the given sentence: Health: [header] How to remember dreams [title] Plan to get a good night's sleep. [step] We have more facility to remember the dreams which occur when our bodies are in the sleeping stage known as rem, which stands for rapid eye movement. The body is at rest, but the mind is active with dreams.

Ending1: If you don't get enough sleep at night, or your sleep is interrupted a lot, you get less rem sleep, and fewer dreams. Try going to bed every night at the same time, and waking up at the same time every morning, to make sure you're getting the right kind of rest. Ending2: This means to get enough rest and to increase the frequency of your dreams. [substeps] This is important because we sleep a lot, which promotes memory retention. Ending3: During rem, we are aware of your body's natural circadian rhythm, which brings you back to wakefulness within 1 to 2 hours. The only way to get a good night's sleep in the dream is to make sure your body has enough rem time to sleep. Ending4: In the morning you will be wired with a melatonin chemistry which influences mental and emotional functioning by the brain's natural internal response to stimuli. This reaction prevents people from falling asleep peacefully when certain stimuli make them highly active.
