We can resolve many of the interpretation conflicts that surround the issue of death by simply keeping the earthly physical body's inanimate state after death completely separate from the soul's spiritual life … Explore the Brain Stem 3D BRAIN Neuroscientist. The REM can differ from person to person, but generally, they are 5-10 minutes in length during the first phase of the night and later it can be around 30-34 minutes.

It is often argued that if the person is not conscious while committing the crime or the person doesn’t remember committing the crime as he /she was sleepwalking, then how can they be charged guilty, but now with this new research, it is being said that there is some consciousness present even when the person is asleep.

(Studies suggest that children under age 10 only dream during roughly 20 percent of their REM periods.). Yes, we do lose consciousness when we die. Our sleep debt is the amount of sleep we have lost due to various causes such as sickness, awakening in the middle of the night, sleep habits, etc.. Gabriel, a listener from the Philippines, asks a very common question: “Pastor John, when we die, does our consciousness continue somewhere? Interestingly, delta sleep is when sleep walking and sleep talking is most likely to occur.
