Hey i recently made my own dread bead out of oak i think and am wondering after i stain it how can I go about sealing or water proofing it so i dont have to take it out everytime i shower

Last night i had what they call an out of body experience. It was actually extremely frightening because i didnt know what was going on at all. I was parlyzed in my bed, not in a way unsimilar to sleep paralasis, but my entire body was vibrating. Almost as if every atom in my body was bouncing off of eachother and off of my skin but internally, if that makes any sense. It was really jarring and when i finally snapped out of it i was sort of afraid to go bak to sleep. It was honestly one of thefreakiest things to have happened. Ive tripped on a substance for spiritual purposes before and the vibrations from that were nothing compared to last night. It was so extremley real I was in full control of my mind but trapped in my body. Im just wondering if anyone else has experienced something like this as well.
