eternal sunshine of the spotless mind is a film about two people who desperately try to erase their own memories about each other. spotless mind is where mind is pure from memories which brings out the eternal happiness (sunshine) state. however as it says here;
“you may forget a past memory but you can’t forget the impulses, instincts and emotions that arose from that past incident”source
expectantly they both try to escape from having their memories erased instead.
