Could this be it?
Been searching for an app to help with sleep paralysis. Going to test this app out. Would be great to see it for apple watch to check heart rate or breathing since its hard to move while being in sleep paralysis. Maybe the watch app could pulse vibrate to help “wake up” the victim. Excited to see if this app works though! Giving 5 stars for the idea and concept , can’t rate on how it works yet!
