Anyone ever feel like they're "THAT CLOSE" to time-travelling?

And no, there's no weed fueling this

I know it's just imaginary, but occasionally, I have a dream (often half-awake) where I feel like I could almost go back to a past moment, like going back down a hall and opening a door. Usually, it's to go see a parent or loved one who is gone, it really feels like I could just 'back up', and visit them again. I'll be somewhat aware, not quite out cold, and it just feels like a little break of inertia would do the trick.
I then wake up and it's weird; you know it's not real, but a little part of you still wants to remember how to take that first step back, and you can then go the rest of the way.

Anyone else have that dream?
