When playing blindfolded, how do you visualize the board? And what orientation do you see it in?

I’ve heard some people say that when they visualize a board in their head, some see it as a flat 2D position like in online, and others see it in 3D like in OTB. As well as this, I’ve heard people say they only visualize from whites perspective with the white pieces on the bottom, regardless if they’re playing black or white. For those who can play blindfolded, what’s your preference?
