Am I seeing and hearing things? What the heck is happening during this speech?

This is downright weird and freaky. Perhaps a sign that his dementia is worsening.

On the bright side, this made me laugh so hard I got a bit of an abdominal workout. The "glitch", whatever is causing it, and the other ways it could affect him cognitively are frightening. The swollen ankles and bruising could very well be the least of his health issues.

If asked by a member of the press about this incident, as he'd better be, I wonder how he'll explain it away.

That's hard to explain, but I'm sure his people will have a fine-tuned answer for his fans.
