But experts can provide estimates about how long you may spend dreaming. According to the National Sleep Foundation, the average person dreams four to six times per night. You might spend as much as 2 hours in dreamland over the course of a night's sleep, reports the National Institutes of Health.
The length of a dream can vary; they may last for a few seconds, or approximately 20–30 minutes. People are more likely to remember the dream if they are awakened during the REM phase.
There are certain exceptions that the dream time extends for longer, especially during lucid dreams where physiological variables are ideal for prolonged dreaming. Therefore, theoretically, the longest dream occurs about 2 hours long, but in practice it is rare, and most dreams last for about 45 minutes at most.
Dreaming sleep is characterized by rapid eye movements known as REM. The longest recorded period of REM is one of 3 hrs 8 mins by David Powell (USA) at the Puget Sound Sleep Disorder Center, Seattle, Washington, USA on 29 April 1994.
How Long Do We Dream Each Night? Researchers estimate that the average person spends about two hours dreaming each night. REM sleep periods early in the night generally last about 10 minutes and gradually increase in length throughout the night to a maximum of about one hour.
If you feel that your dreams last for so long it's a good sign you're entering the REM phase of sleep many times during the night. This is a good sign, although it may feel a little exhausting if your dreams are bombarding you with messages.
Dreams can happen during any stage of sleep, but the vivid ones that you remember tend to happen during REM sleep.
Overall, researchers and study participants agreed that black and white dreams were the norm, and rare cases of coloured dreams were dubbed 'Technicolor' dreams (Calef, 1954, Hall, 1951), highlighting their perceived artificiality. This tendency to report black and white dreams suddenly disappeared in the 1960's.
We Dream Every Night
During a typical lifetime, people spend an average of six years dreaming.
Good sleep has been connected to better cognitive function and emotional health, and studies have also linked dreams to effective thinking, memory, and emotional processing. In this way, many experts believe dreaming is either a reflection of or a contributor to quality sleep.

Being stuck in a dream that you can't seem to wake from could indicate a need to mix things up in your daily life — as it may be a metaphor for feeling stuck or stagnant in your current routine.
Shared dreams definition
Shared dreaming is the idea that two or more people can share the same dream environment. The degree to which the dream is shared can vary, from simply having common elements or events that happen in each person's dream, to the entire dream being identical.
Lucid dreaming happens when you're aware that you're dreaming. Often, you can control the dream's storyline and environment. It occurs during REM sleep. When used in therapy, lucid dreaming can help treat conditions like recurring nightmares and PTSD.
Dreaming may be a cultural universal, but it is clear that some individuals recall few or no dreams over many years—and that these individuals suffer no ill consequences from their apparent inability to dream. Dream recall may not be necessary for mental, physical, or cultural health.
Although their visual dream content is reduced, other senses are enhanced in dreams of the blind. A dreaming blind person experiences more sensations of sound, touch, taste, and smell than sighted people do. Blind people are also more likely to have certain types of dreams than sighted people.
Yet many people who have recovered from comas report dreams into which something of the outside world penetrated. Others recall nightmares that seemed to go on and on. Whether they dream or not probably depends on the cause of the coma.
A very small percentage of Americans — just one in 10 — say they always remember their dreams, while an equally small percentage say they never remember them. For most Americans, it's somewhere in between. Women are more likely to report remembering their dreams than men, but there is a larger difference by age.
Good naps are often dreamless.
It typically takes over 45 minutes to enter REM sleep (the stage during which you dream). “If you are having dreams during your nap, this could be a sign that you aren't getting enough REM sleep at night,” said Dr. Panah.
It is unusual for dreams to occur soon after falling asleep since the first cycle of REM sleep is usually around 90 minutes after falling asleep. They then occur at approximately 90 minute intervals during sleep and are most complex and prolonged in the later REM sleep episodes towards the end of the night.
Rapid eye movement (REM) sleep, or stage R, usually starts about 90 minutes after you fall asleep. Brain activity increases, your eyes dart around quickly, and your pulse, blood pressure, and breathing speed up. This is also when you do most of your dreaming.
Although some theorists have suggested that pain sensations cannot be part of the dreaming world, research has shown that pain sensations occur in about 1% of the dreams in healthy persons and in about 30% of patients with acute, severe pain.
1. Being chased. Being chased is one of the most common nightmares. If you dream that you're being chased by something, whether it's an 8-foot-tall rabbit or a shrouded figure, then it's an indicator that you're running away from something or someone in real life.
Researchers say two-way communication is possible with people who are asleep and dreaming. Specifically, with people who are lucid dreaming — that is, dreaming while being aware you're dreaming.
Most recurring dreams are assumed to reveal the presence of unresolved conflict or stress in the dreamer's life. Recurrent dreams are often accompanied by negative dream content, that is associated with lower psychological well-being.
