I've had vertigo that felt like it was sucking me down into a drain or maybe suddenly making it seem like gravity had gotten a lot stronger. It came up one side of me, hit my head, made me feel like the ground had just disappeared and then went down the other side of me, pulling me down with it.

Once I was sucked to the floor, or pulled down into a chair or onto a bed, it felt like I was being twisted in every direction, back, forth, up down, sideways...

Very disturbing when the vertigo can hit you in seconds like that.
