I have been in deep water where if the bottom exists it is out of sight. Of course it exists and you know it does, but knowing and seeing are two wildly differently things. The problem with insane deep water is that your mind loves to populate it with giant beasts.https://qph.cf2.quoracdn.net/main-qimg-e46f9a9f038f5989705917beccecb261
