Since the brain is the controller of the body, a tumor's presence can cause almost anything in the body to become dysfunctional. Most frequently the diagnosis of someone who falls asleep abruptly and without control is Narcolepsy.
Neurotransmitters in the brain are in charge of whether someone is asleep or awake. When the brain begins to produce neurotransmitters like melatonin, someone will begin to feel sleepy.

brain mcknight
yes. when someone feels light headed or dizzy, that is a sign of the lack of oxygen to the brain. since your blood is what carries oxygen, anytime there is a loss of blood to someones brain it does not get enough oxygen and that is when people pass out.
Even when your asleep your brain is still at work. When we fall asleep we go through different stages. Some scientist think that when you fall asleep the brain sorts information it has been receiving during the day. Some information gets rid of and some gets filled in your memories. :)
If someone is in a coma they are unconcious and do not respond to voices,sounds or any activitie around them.He is still alive but their brain is working at it's lowest standard/stage of alertness.If you shake someone and their in a coma then they do not wake up like if you shake someone that's asleep.
because your asleep, your brain is not functioning well, or you could be dreaming a good dream
it is most active when your asleep because it goes over what you did, learned, and saw.
Safely? No. You can do it, but it's not safe. You pass out because of lack of oxygen to the brain. Anytime the brain becomes hypoxic you run the risk of minor to severe brain damage. Many people have died because of this practice and they are usually teenagers.
False
Usually you dream. You're brain is more active when it's asleep than it ever is when you're awake.
Not necessarily. The brain is constantly working regardless of whether you're awake or asleep. Some areas, however, will be more active when sleep and some when you're awake.
