Dreams Informative Speech

Hello my name is and I would like to start by asking you to sit back and close your eyes, but then again you may fall asleep. I would prefer you not to do that, but if you were to, you might just experience the very thing I am going to inform you of today. And thats about Dreams

Dreams are something we all experience every night, whether we remember them or not. 1/3 of your life is spent sleeping, and in that time, you all will experience thousands of dreams. The 3 key items I want to talk about are dream theories, how a dream works, and if we can really interpret our dreams.

Those theories essentially fall into two categories:

* The idea that dreams are only physiological stimulations and * The idea that
Many researchers and scientists also believe that perhaps it is a combination of the two theories.

I would like for you to understand that there are numerous theories about dreams, but whomever you are, where ever you live, you will dream. Whether it's a good dream or a nightmare is up to your own mind. Now let's look a little deeper into what actually happens in the brain when we dream.

When we sleep, we go through five sleep stages. The first stage is a very light sleep from which it is easy to wake up. The second stage moves into a slightly deeper sleep, and stages three and four represent our deepest sleep. Our brain activity throughout these stages is gradually slowing down so that by deep sleep, we experience nothing but the slowest brain waves delta brain waves. About 90 minutes after we go to sleep and after the fourth sleep stage, we begin REM sleep.
Rapid eye movement known as (REM) was discovered in 1953 by University of Chicago researchers Eugene
Aserinsky, and Nathaniel Kleitman. REM sleep is
The rest of the body, however, is essentially paralyzed until we leave REM sleep. This paralysis is caused by the release of glycine, an amino acid, from the brain stem onto the motoneurons (neurons that conduct impulses outward from the brain or spinal cord). Because
REM sleep is the sleep stage at which most dreaming takes place, this paralysis could be nature's way of making sure we don't act out our dreams.
Otherwise, if you're sleeping next to someone who is dreaming about playing kickball, you might get kicked repeatedly while you sleep.

The four stages outside of REM sleep are called non-REM sleep
(NREM). Although most dreams do take place during REM sleep, more recent research has shown that dreams can occur during any of the sleep stages. Tore A. Nielsen, Ph.D., of the Dream and Nightmare
Laboratory in Montreal, refers to this as "covert REM sleep" making an appearance during NREM sleep. Most NREM dreams, however, don't have the intensity of REM dreams.
Throughout the night, we go through these five stages several
