Hiya everyone, happy new year! Writing this from a throaway account for obvious reasons.I'm a middle-aged (38 yo, male) solo founder of a bootstrapped B2B startup, and for many years I have experienced various sleep disorders, in particular night terrors or arousals in which I wake up with my heart pounding, often hallucinating that there's something in the room or outside the window trying to hurt me or my bed partner. Sometimes I then jump out of bed, shake awake my bed partner or try to drag her out of (imagined) harm's way, throw away the blanket or a pillow or turn on the lights. I never thought much about this kind of behavior since it occurred quite infrequently, recently I've been reading about REM based sleep disorder though (which is an early symptom of a neurodegenerative disease) and I'm worried I might have that. Both of my grandfathers died from such diseases (Parkinsons' and Alzheimers's, respectively), at high ages though, which adds to my fear. To get to the bottom of this I plan to do a polysomnigraphy sometime this year, until then it seems I have to continue worrying about it.Has anyone here experienced similar sleep disorders? I once read that starting a startup can cause symptoms that are similar to PTSD, which can include things like night terrors or nocturnal panic attacks, but I never made the connection before. Recently I have been experiencing these attacks a bit more often again, and while this year I have seen some first success for my startup it has also been quite difficult due to Covid-19 and the reduced potential to network with clients (we're in a B2B market and relied heavily on our personal network and events like conferences or business fairs to find clients), and we risked running out of cash several times.I'd highly appreciate if you can (anonymously) share your experience. Any ideas how to deal with this beyond trying to get it properly medically examined? Thank you!
