Because dreams are such vivid illusions, during normal sleep, we can’t tell the difference between that illusion and reality. The images you see in your dreams tend to be familiar because dreams are how your brain processes information and memories, and while our brains “see” in dreams much like we imagine or envision our potential futures. Some people are even conscious enough within their dreams to manipulate them and direct what happens, which can make lucid dreaming an adventure in possibility. This occurs when you’re “aware” in the midst of a dream. Lucid DreamingĪbout half of all people have experienced lucid dreaming at least once in their life. Often confused with sleep apnea because sleep paralysis can sometimes interfere with breathing, sleep paralysis is a totally different issue marked by awareness (you are conscious) and it’s often accompanied by hallucinations, while sleep apnea is not. It’s bad enough when this happens in a dream, but when it happens in real life you can quickly become consumed with utter panic! Some people are even convinced that a force is holding them down (aliens, witches, old hags, anyone?) or the paralysis might come with hallucinations of demons or intruders.įortunately, sleep paralysis (also known as “Old Hag” Syndrome ) isn’t harmful, and it only happens on the brink of wakefulness and sleep – either as you fall asleep (hypnagogic or predormital) or wake up (hypnopompic) – and it’s often an indication that your body is struggling to transition through the stages of sleep properly.Ī common problem with about 40% of people experiencing it, sleep paralysis can be either occasional or frequent, and it can run in families.

One of sleep’s most terrifying situations is waking up or falling asleep and being totally unable to speak or move. Today we’re breaking down strange sleep phenomenons so you can rest easier at night.

Whatever your weird sleep story might be, you’re actually not alone. "In that case, life might really struggle to get started out of phosphorus-poor chemistry, on another world otherwise similar to our own.Strange, unexplained stuff can happen while we sleep.įrom sleep paralysis to seeing strangers in your room to sleep talking and feeling as though you bed is covered in bugs, some sleep phenomenons aren’t just weird, but terrifying. "That is, it started off near the wrong kind of supernova? "If phosphorus is sourced from supernovae, and then travels across space in meteoritic rocks, I'm wondering if a young planet could find itself lacking in reactive phosphorus because of where it was born? "We already think that only a few phosphorus-bearing minerals that came to the Earth, probably in meteorites, were reactive enough to get involved in making proto-biomolecules. Phosphorus is created in supernovae, exploding massive stars at the end of their lives.īut the new research suggests that typical supernovae may not provide the conditions needed for forging the element.Įarth may be unusually lucky, because it happened to be situated close enough to the "right" kind of supernova.Īstronomer Dr Jane Greaves, from the University of Cardiff, said: "The route to carrying phosphorus into new-born planets looks rather precarious. The element is vital to energy storage and transfer in cells, and is part of the chemical backbone of DNA.

Alien life may be more unlikely than commonly thought, according to a UK study that hints at a cosmic lack of phosphorus.
