Twitching.

Thanks to those who gave input and information. She’s at the end stage of dementia and can’t tell me what’s going on. Very limited vocabulary.

You asked this exact question on April 12th and received some good replies:

My husband has been twitching in his sleep for 15 years or more.
Now he also twitches during waking hours.
Had every tests done, nothing conclusive.
However, myoclonus is common with Parkinson’s disease.

Twitching is very common in sleep.
I would call, not see the doctor. I think you will be reassured by speaking to him/her.
This is very common. Ask administration to observe for this in waking hours. This is likely deep REM sleep and dreaming. Nothing to be concerned about if there is no daytime problems observed.

My husband does this when he lays on his back. He doesn't get enough air.

My dad did that a lot, more like a little jump or jerking in his sleep. Nothing to be medically worry some, maybe some sleep aid so she can get more restful sleep, if it continues

It's nothing medical to be concerned about:

"Sleep myoclonus causes involuntary muscle twitches during sleep or when a person falls asleep. In some cases, sleep myoclonus occurs on its own without an identifiable cause. Sleep myoclonus can also develop as a result of a sleep disorder or a neurological disorder."

and

"Hypnic jerks are a normal, albeit unpredictable, part of the experience of falling asleep."

Doesn't require a doctor's visit.
