▲Nothing like waking up in the morning and starting the day after a good night's sleep.

▲For many people, sleeping is synonymous with nightmares.

▲Though not everyone seems to be affected by bad dreams. Alice Cooper, for example, recorded an album called 'Welcome to My Nightmare.'

▲But this is not the case for most people. After all, who has never had a nightmare involving a creepy creature from a horror movie?

▲Who never regretted having watched that intense scene on a TV show before going to bed? Or had a horrible dream about the death of a relative?

▲But what are the possible explanations for these horror films that go through our minds while we're asleep?

▲According to scientists, nightmares usually happen at the deepest stage of our sleep. This phase is known as REM and lasts about half an hour, and can be repeated on average up to 6 times a night.

▲According to the same study, themes such as death, threats, and health concerns, were also predominant in the reports.

▲According to a 2014 study conducted by the University of Montreal in Canada, one of the most recurring themes of nightmares is physical aggression.

▲In another study, researcher Gary Fireman stated that nightmares are ways of expressing emotions that we are unable to express when we're awake.

▲If you have had some sort of trauma and this is the most recurrent theme of your nightmares, it is advisable to seek professional help.

▲

Do you remember having the same nightmare more than once?

According to Gary Fireman's theory, this phenomenon is due to repressed desires and frustrations, which are stored in our subconscious.

▲Having the same nightmare over and over again may be a way of your subconscious mind drawing your attention to a particular issue.

▲We know that the brain is capable of creating a lot of activity while we're asleep. But is there anything we can do to stop having nightmares?

▲The answer is no, but there are a number of habits that can improve the quality of your sleep and consequently contributing to you having less nightmares.

▲Getting anxious the night before an important event can literally turn into a nightmare, so try to relax as much as possible.

▲Some medications can also contribute to having nightmares. Remember that any medication should only be taken if prescribed by a doctor.
