Deja-vu

What if one day I stand in the middle of a moment, totally strange with no idea of how I got there with no past memories. Everything seems familiar only after engaging with them. What if then I say I have a party to attend to, what if my feelings are real, like these things are already happened, I wish I could hold on to such feelings so I could use for the future, but it is something we need some ability to. What if we could fix that moment for at least a few seconds, we could have saved ourself from feeling the suffocation we feel when we try to capture it like right now.
