It could be from being cold. And maybe just holding it in while awake.
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.
FALLING
An apple falling from a tree.
Someone's hand can fall asleep due to lack of circulation to the hand. When a person sits, or lays a certain way the circulation can be restricted if pressure is placed upon any one part of the arm or wrist. To regain circulation a person can move their arm and hand around to cause the blood to begin to flow back to the hand and the feeling of it having 'fallen asleep' to be removed.
About, afoot, ago, along, aside, asleep, atop, awake.

Sonny and Chad begin officially dating. It's called "Falling for the Falls" because Chad tells Sonny that when she falls for him, she falls for his show, too.
This is a normal and not uncommon experience. When you are just going to sleep or more commonly when you are waking in the morning, you may enter a period of being half awake. Sometimes these experiences are called hypnagogic if experienced when awakening. When they are experienced during the process of falling asleep they are called hypnopompic. They can seem like hallucinations, but they are not caused by any pathology. There are systems in place to inhibit motor activity and sensory input while asleep; this is what causes the stupor that we experience when asleep. We sometimes begin to regain some consciousness before these systems have completely restored our motor and sensory faculties.
I have no clue..someone help me out..
You need to specify the question. If they are falling...from how high up are they when they begin to fall?
Well since it is buoyant, it rises until it cools enough to begin falling again.
