Transtemporal (смешанная)

Kakashi crashed face-first into the hardwood floor, his body felt as though he suffered the worst case of chakra exhaustion to date. But immediately, his eyes snapped open in realization. He wasn't supposed to be lying on a floor. He had been fighting Pein in the attack, and died.
So what was he doing on a hardwood floor?
Groggily getting up, his eyes scanned about the room, trying to ascertain his location. His breath hitched. He remembered this room vividly, this was the very same room his father had committed seppuku. Although Kakashi had somehow come to terms with it, waking up in this room wasn't his cup of tea at all. Staggering to the door, he was about to open it when the door slid open.
There, before him, was his younger self, staring up at him with those innocent onyx eyes.
"Dad? Are you okay?"
Kakashi froze. What the fuck?
