Dreaming that you caress somebody shows you may not be treating the people around you well, as they deserve. If you are the one receiving caresses by others then it means you do not have all the affection you need in real life.
Types of sleep
There are two types of sleep that most of the humans undergo - REM and NREM. REM refers to the Rapid Eye Movement and NREM refers to Non-Rapid Eye Movement. Every individual will alternate these two types of sleep. Non-REM sleep will occur for a short period of time in the first stage of your sleep followed by the REM sleep. Dreams occur during the REM stage, where it lasts for 20 minutes. According to a researcher, J. Allan Hobson, dreams that occur in REM stage are usually forgotten when the individual wakes up. Studies conducted on patients during sleep shows that the frontal lobes in the brain, that are responsible for storing information, are inactive during the REM stage, which is the main cause for forgetting the dreams. Studies also show that this is the stage where you have the most intense dreams.
The amount of sleep that a person gets will be associated with his or her lifespan. However, the causes or effects are still vague, as illnesses can also affect a person's sleeping pattern. According to a 2010 study, women under the age of 50 to 79 only get less than five hours of sleep every night, which makes them a subject for death occurrences.
