User blog:Luna Heartstring/What does a Reset feel like?

So I'm in the middle of writing out a parody of a song for Undertale (My second one to date) and for one of the lines in the song I want to know what a Reset feels like.

From what I've gathered it seems to feel different to each character. (Papyrus feels as though everything is familiar and that he has Deja vu.)

What I want to know is that if there's a particular feeling involved, what happens if you're not at the point you are when the character first meets you and why doesn't anyone but Sans know about the Resets?

I went back and checked out the Dialogue for Sans's battle. Nothing really spiked my attention until he said "You can't understand how this feels. Knowing that one day, with ought any warning... It's all going to be Reset."

He went on to say that he gave up trying to go back and he didn't want to go to the surface either. (Which raised some questions that I'll make a blog about later :D)

So that leaves me with the question... What does a Reset feel like?
