dealer 20 streak

Dealer pulled a 20 on me seven hands in a row and I started second-guessing if my play was right or if I was just running cold. I keep my charts handy and mostly stick to basic strategy, so I don't think it was anything wild in my decisions. Just weird to see the same outcome over and over. Felt almost like the table was rigged but I know variance is a thing and streaks happen. Still, it got in my head and I switched tables for a bit.

I've read people say to just play through it and ignore the streaks, but honestly, after four or five dealer 20s in a row, how do you not tilt or start chasing? Do you guys have any tricks for staying calm or resetting your mindset when a run like that hits? Does switching tables actually help you, or is it all just in our heads?
