Very strange sensation?

Did you ever figure out what this is? Did it go away?

The exact same thing happens to me, i get episodes of it when my anxiety comes back

I describe my strange sensation as having an old tube type TV (very old, 300 lbs console TV old) and the plug is loose in the outlet. Every time the plug gets bumped by the cat walking behind the TV the TV almost cuts off for a split second. The picture almost goes out, but as the cat keeps walking by the plug it reconnects and the picture and sound flash back on. The fade out then back on has lasted only a split second so the picture comes back on and everything is fine. For that split second I feel like death is upon me, but then i feel absolutely fine, until it happens again. Sometimes it happens multiple times in a very short time frame. Other time it doesn't happen for weeks or longer. Recently its been happening a lot. I should acknowledge that I'm under a lot of personal stress. My wife has Alzheimer's, selling our home of 40 plus years, living in a new place, not enough sleep, (like everyone else is going through).

Anyone have any ideas?

omg im feeling the exact same way but didnt know how to discribe it..its scary

I want to pick this thread back up. I've been experiencing the same thing as you guys when going to sleep. A light switch just goes off for a split second and I'm gone. I come back in a panic because it felt like I was fading away. For me it's not because I don't get enough sleep, but my sleep schedule is off. like if I go to bed later than usual then it's more likely to happen. even when I come out of it I panic because I'm sometimes in a state of either depersonalization or derealization, because i come out either not knowing who I am or where I am or what anything is. it's also more common to happen if I sleep on my left side instead of my right. In fact it's guaranteed to happen if I sleep on my left side or my back. it can still happen if I sleep on my right but it's not guaranteed. I also think nicotine might have something to do with it? seems to be more common if I smoke later in the evening. it's possible that it's stress related considering that nicotine can increase anxiety but idk. it's just so weird. the best things I do to avoid it are go to bed earlier, don't smoke too late, don't sleep on my left side.

yes been experiencing this for several weeks now and it is happening several times a day, im now getting concerned about it.

Jumping in here and set up an account just so I can check back. I see all the posts are old from 10 months to 7 years, but there is NOTHING online to explain this. Like most of you, I get occasional heart palpitations, which aren't that crazy, but THIS is like dying for a split second. Like....that feeling of the power shutting off for just the span of a blink. All sound and everything is gone. Then the switch flips back and the big power surge hits me and I'm panicking. It's mostly at night, but it has happened in the full light and activity of day. It is the scariest freakiest thing, and while I hate that you all are feeling this too, it's comforting to know I'm not crazy and this is real. Nothing online explains this. Not really. They talk about brain zaps coming off meds, but that's not my situation. Has anyone been diagnosed? I don't even know how to describe this to a doctor. "Hey, Doc, I need new spark plugs, mine are shorting out?"
