Reverse osmosis

Explanation:

In order to purify the water which has been contaminated with salt and microorganisms, reverse osmosis will be the best way. In reverse osmosis a pressure is applied on the salt side of the impure water using a pump. Doing this prompts the pure water to leave the salt side so pure water moves another side of the semi permeable membrane. The semi permeable also filters the microorganisms. Hence, pure water can be obtained easily from this impure sample. The RO at our houses use this process to purify water.

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.
