I can't offer you any solutions but I can say I have felt both of the sensations you experienced. I was in a store at its grand opening in November and it was very crowded. I soon became quite dizzy and realized that if I did not get out of there they would be picked me up off the floor (or at least my trampled remains). I did make it out but it took an hour or more for the dizziness to subside. My daughter who is an emt said I had a panic attack even tho the only symptom was dizziness. She said most of the cases of panic attack she treats are limited to dizziness.
As for the floor shaking, I used to feel that while I was sitting at my (tower) computer. I would be noting the time so I could follow up and see if there were any slight earth quakes then but apparently it was only me, no earth quakes. I can say tho that I have not "felt the earth move" for several years now; in fact, I had forgotten about it until you mentioned it. Perhaps it is an ASD thing. Hope yours goes away soon too.
NeilM thanks for your reply and we'll wishes. To clarify, I think the ground was actually shaking slightly because of it being an elevated concrete slab. When I mentioned previous instances of this to dr/friends etc they also told me it's probably panic attack or social anxiety, but that didn't sit quite right with me... when u were sitting at your computer was it in an office building? I used to work in an office building and you could feel the floor shake from people dropping weights in the gym downstairs (this was actually verified because management had to ask gym goers to be more careful with the weights)
I think people with heightened sensitivity to the physical world are sensing actual occurrences - even though they may not be important or useful things to sense...!
