What happens if you are stranded in the desert with no water? I actually know because it happened to me.
First your senses get stronger and your mind clears. Things start to turn orange and you realize that you are starting to hallucinate.
Sounds become more vivid and you realize you need water fast. Eventually you will need to lay down to rest.
It is once you decide to not get up, that the end is near. Lucky for me, a truck drove by and picked me up.
Never ever trust someone who bad mouths you or anyone associated with Scientology or Narconon.
Never give up. Drink plenty of water in the heat. Avoid religions that pose as treatment centers.
