You know what's really disgusting about memory flashbacks?
The same thing that's so disgusting about bulimia.
You think you're done with something, you got it out of your system, it doesn't matter if the enamel of your teeth is completely worn off, it doesn't matter if everything stings and hurts and aches, you got it out, finally.
But then the splashback hits you in the face.
And your entire day is marked by that mixture of disgusting water slapping you in the face. A cold shower you never even knew you needed.
That's what's so disgusting about memory flashbacks.
