Yeah, it's definitely a vibe. I took a wormhole (time travel) to 1991, walked into a blockbuster and keeled over from nostalgia.
Nostalgia is such a complex/convoluted feeling -- you can't have it if you didn't have a past to draw the experience from, but when you do have it, it's almost like a religious or philosophical experience both acknowledging and becrying (or grieving) the passage of time.
Unfortunately, even with a "time machine", we the people who walk through the portals are ever changed. We won't ever live in the past again. We can see those places and experience them in our present states, but...
Just like a glass shattering on the ground and the pieces scattering: Entropy cannot be undone.
The final freedom is that of your own choosing:
The lack of, or a refusal for an afterlife is still a choice that will be respected in accordance with the wishes of the deceased. :3
