What is dreams

Dreaming can happen during any stage of sleep , but dreams are the most prolific and intense during the rapid eye movement REM stage. During the REM sleep stage, brain activity ramps up considerably compared to the non-REM stages, which helps explain the distinct types of dreaming during these stages. By contrast, non-REM dreams tend to involve more coherent content that involves thoughts or memories grounded to a specific time and place.

REM sleep is not distributed evenly through the night. The majority of REM sleep happens during the second half of a normal sleep period, which means that dreaming tends to be concentrated in the hours before waking up.

How to interpret dreams, and whether they have meaning at all, are matters of considerable controversy. Virtually all experts acknowledge that dreams can involve content that ties back to waking experiences although the content may be changed or misrepresented.

For example, in describing dreams, people often reference people who they recognize clearly even if their appearance is distorted in the dream. The meaning of real-life details appearing in dreams, though, is far from settled. Dreams can take on many different forms.

Lucid dreams occur when a person is in a dream while being actively aware that they are dreaming. Vivid dreams involve especially realistic or clear dream content.

Bad dreams are composed of bothersome or distressing content. Recurring dreams involve the same imagery repeating in multiple dreams over time. Even within normal dreams, there are certain types of content that are especially identifiable. Among the most recognizable and common themes in dreams are things like flying, falling, being chased, or being unable to find a bathroom. This definition is distinct from common usage that may refer to any threatening, scary, or bothersome dream as a nightmare.

Dreaming is part of healthy sleep and is generally considered to be completely normal and without any negative effects on sleep. Nightmares are the exception.

Because nightmares involve awakenings, they can become problematic if they occur frequently. Distressing dreams may cause a person to avoid sleep, leading to insufficient sleep. When they do sleep, the prior sleep deprivation can induce a REM sleep rebound that actually worsens nightmares. This negative cycle can cause some people with frequent nightmares to experience insomnia as a chronic sleep problem. For this reason, people who have nightmares more than once a week, have fragmented sleep, or have daytime sleepiness or changes to their thinking or mood should talk with a doctor.

A doctor can review these symptoms to identify the potential causes and treatments of their sleeping problem. For people who want to document or interpret dreams, remembering them is a key first step. The ability to recall dreams can be different for every person and may vary based on age. Remind yourself that dream recall is a priority. In the lead-up to bedtime, tell yourself that you will remember your dreams, and repeat this mantra before going to sleep.

People with frequent nightmares that disturb sleep should talk with a doctor who can determine if they have nightmare disorder or any other condition affecting their sleep quality. Treatment for nightmare disorder often includes talk therapy that attempts to counteract negative thinking, stress, and anxiety that can worsen nightmares.

Many types of talk therapy attempt to reduce worries or fears, including those that can arise in nightmares. This type of exposure or desensitization therapy helps many patients reframe their emotional reaction to negative imagery since trying to simply suppress negative thoughts may exacerbate nightmares. Another step in trying to reduce nightmares is to improve sleep hygiene , which includes both sleep-related habits and the bedroom environment.

Healthy sleep hygiene can make your nightly sleep more predictable and may help you sleep soundly through the night even if you have bad dreams. Examples of healthy sleep tips include:.

Dream Analysis, Past Tense Version. All is well for the most part… Just outside of ten minutes left in the dream I hear a local foreclosure lockout curfue is about to go into effect and all non-Tampa residents must leave the city before their former property is destroyed and they be arrested.

Funny enough, on exactly Tuesday, November 6th of at around 6 PM, me and my mom foreclosed from the childhood house by signing foreclosure documents and moved out here to Valrico permanently never to travel back west for any reason.

At the end of some of these dreams, just the house would be cited by a natural disaster or the immediate neighborhood. One time I got lucky to see the entire city of Tamp and even the surrounding cities of St. Petersburg and Clearwater wiped off the map as if the entire region never existed. After a few seconds in the dream, the destruction made national news and a banner showed up on my tv screen.

It means nothing to you in the end. If at any point a likeness of me is spotted in Tampa in this building now, gunshots go off at point-blank range, not hitting me but rather the ghost formations of me from my past and shattering them like glass in a china closet. I woke up from one such dream thinking I heard our ambulance with the electromechanical siren go by. Sure enough, the ambulance was just going by down Valrico Road at full board.

Prior to this dream ending, it sounded as if the siren was being slowed down like it was on a record still spinning that would take a year to come to a complete stop yet I had the luxury of being able to listen to the record come to the full stop. At that exact point everything in the dream just self-destructed even the ambulance too and I wokr up. Some are longer and some are shorter. What could this mean? Its so bizarre to me!
