I can't find where everything was copied from, but the above source has an entire paragraph you copied and pasted

Your paragraph-The reason sleep paralysis may explain tales of ghosts and aliens that has a strong sense of presence, usually harmless, the victims usually experience during an attack. You mentioned unusual kinesthetic sensations, such as feeling that they're being pulled out of bed, vibrating, flying or falling. These episodes can sometimes lead to the feeling that you are out of your body. Sleep paralysis can be scary, but never dangerous, and thankfully, episodes usually last only a few seconds.

Source paragraph- The reason sleep paralysis may explain tales of ghosts and aliens is the strong sense of a presence, usually harmful, that victims commonly feel during an attack. They also report unusual kinesthetic sensations, such as feelings of being dragged out of bed, vibrating, flying or falling. These episodes can sometimes lead to full-blown out-of-body experiences. Sleep paralysis may be frightening, but it is never dangerous, and thankfully, episodes usually last only a few seconds.
