I suspected an incident in 2025 may have played a part, but I'm not sure, due what seems to me to be the lack of a clear pattern.
My sibling whom I was close with in childhood died suddenly in their 30s last year, contributed to by fault of medical staff. I considered this traumatic, but besides trouble sleeping the night I was told by my parents of the death, I don't think I've noticed a clear pattern since then. Random wakes with subjectively heavier pulse for several weeks in late 2025 I attributed to elevated heavy metals of arsenic, mercury, thallium (since resolved via diet changes). By the time I started noticing the sleep myoclonus shortly before March, it had already been a half year since sibling's death.
A related event I also consider traumatic was watching the hospital CCTV footage of my sibling dying that had recently been released to my family, when I took detailed notes of my sibling's movements and of medical staff recovery attempts afterwards. I thought this would mess with my sleep, but that was the evening of 4/14 which I noted in a prior post - fell asleep within 5-10 minutes with just melatonin, 0-1 wakeups and over 7h sleep, no myo noticed. This is despite stopping the video before I finished logging it due to subjective distress, deciding to complete logging it the next day after returning subjectively more detached (which I did, and I don't have anything logged for my sleep on the evening of 4/15 either so I guess I slept fine that night too). So again, to me it seems there's no clear direct 1:1 relation between these incidents and sleep.

Sleep transition performance has been hit/miss last 5 days.
Evenings of 4/16, 4/17 and 4/19 were relatively normal, 7-8+ hours of sleep per night, in one case possibly 9h when including naps next day. Melatonin drops 1mg on 4/16, 4/17, nothing on 4/19. Recorded up to a few myo (including teeth click) on 4/16 and maybe 4/19 but was able to ignore it and get to sleep quickly after.
Evenings of 4/18 and 4/20 contrarily: reached N2-N3 only after 4am despite being in bed for hours (likely contributed to by late wakes preceding day). 4/20 evening, again experienced more than a few myo (including teeth clicks) and random N1 wakes. 4/18 also had up to a few myo and maybe an N1 wake but I attributed the restlessness largely to DSPD. On 4/18 I eventually took a Dayvigo; on 4/20 I withheld taking one again so soon, but eventually reached N2/N3 likely between 4-5am. On 4/20 I exercised relatively late (past 9pm) which I guess probably wouldn't help.
On both 4/18 and 4/20, after a few hours of failing to pass N1, I listened to the Sleep With Me Podcast (downloaded some full episodes and had them on shuffle repeat) which seemed to help due to the monotone voice and nonsensical "dream-like" chatter (although the voice itself generally seems enough).
Although transition on 3 of the 5 preceding nights were normal, notably, myo were still noticed on most of those nights (including teeth clicks, but also, especially 4/20 evening, subtle movements of jaw, eyebrow and other body parts, like was more prevalent for a few nights within the last few weeks, although not as bad as when I initially posted this thread), something I rarely or never noticed before early March besides the rare hypnic jerk. Since they're still occurring, I'll probably talk to another doctor and try to get a free sleep apnea testing kit and/or other suggestions. Also debating whether to get an enhanced full-body MRI at Prenuvo which includes a brain health assessment (https://www.prenuvo.com/enhanced-screening) in case there's anything neurological going on that can be detected via imaging. It's expensive but there's a member return discount lasting for another month. I did a regular whole body scan with them a few years ago with no regrets.
@cmx, you are a careful and comprehensive recorder of what is happening to you. Healthy sleep is so critically important for our quality of life during our daytime hours as well as our nights. Trust your own judgment regarding what may be happening and what's needed. I wish you well as you sort this out.
