A dream is a series of images, emotions, or sensations that our brains create while we sleep. Scientifically, dreaming can occur during any stage of the sleep cycle, but REM sleep or Rapid Eye Movement sleep is the dream that produces the most memorable and vivid dreams. 

There are various types of dreams which include healing, prophetic, lucid, nightmares, and three other more. If you are curious to know each one of them, click here. 

Multiple dreams per sleep are possible, and they can be as short as 10 seconds or as long as 45 minutes. Some people are even able to continue their dreams until several hours even after being cut in a short wake. While until now, there is still no clear scientific explanation for why humans dream, there is a range of theories. One of the most popular reasons from psychoanalysts is that dreams are a repressed longing. 

Here are some of the most common dreams that people normally have and their meanings.
