most obvious effect of gravity - things falling down - can be eliminated by making the transition to a reference frame that is in free fall, and that in such a reference frame, the laws of physics will be approximately the same as in special relativity.
could this mean that stimulating a past event can bring you the same experience in the past, as if you were experiencing it again?

Both are true, but unrelated. The first is the Principle of Equivalence.
The second is just how human memory and emotion work. When I first went to my original home and neighborhood after 5 years away, the flood of emotion was phenomenal. Seeing a photo of someone who was an intimate part of my life for years stimulates a large body of memories. Smell is particularly strong at doing this.

experiencing the past again depends on your mind, you observe
inertia frame in free fall because everything around you is also accelerating in the same magnitude and direction. it has nothing to do with "spacetime memory".
Generally experiencing the same condition as in the past will not create the same feelings as you have the memory of it already.
