Dreaming of being murdered again, I awoke in the night attacking the bed rail. I’m reliably told that I violently shake and thrash about all night every night; often shouting profanities, sometimes screaming in terror so loud I wake myself up. Anyone sleeping with me risks being inadvertently hit in the face. I’ve read that such sleep disturbance is correlated (97%) with later development of Parkinson’s, Lewey Body Dementia, or MSA.
