How does an air pump work

The inlet and the outlet are used to direct the flow of air, while the piston is used to generate the flow of air. when the piston is pulled up, air gets sucked in and gets sucked into a pump throught the inlet. When the piston is forced down the air becomes compressed closes the inlet. Then air flows out from the outlet.

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.
