<human>: Yeah of course this didn't happen today. This happened about 5 years ago in Tokyo, Japan.

So while in Japan I had a pretty irrational fear of cockroaches(didn't stay irrational for long). And since I stayed with my grandparents in a small small apartment there were always cockroaches running around and I'd pretty much freak out and jump a little bit when i see one. My mom bought a small rubber cockroach to prank me while I was sleeping. I woke up and saw a freaking huge cockroach on my face and flipped my shit. Then I figured out it was fake and got real pissed. Then for the next few weeks they kept doing this for me and since my natural instincts told me to flip my shit that's what happened pretty much every time... Then one day I wake up in the morning and I see something resting on my chin and I finally had enough of this shit and since my mouth moved a bit it fell into my mouth.... Me being a dumbass and thinking it was fake Just to prove a point I bit the damn thing in half and spat it out. Right away I realized that was not rubber and that in panic I swallowed one half. The other half was squirming on the floor and I proceeded to scream like a girl and run to the bathroom and try to puke that shit out. Wow was I freaking out and my family didn't understand what the hell was wrong with me until I gave up trying to puke and they asked me what was wrong. I then point to the floor where there's a little half cockroach still moving (they still move even when bit in fucking half) and they just start laughing because they're all assholes. I didn't get sick surprisingly or anything and not my irrational fear of cockroaches is multiplied so much and now when I sleep I have to cover my fucking mouth in a bandana or blanket so I feel like I'm not gonna swallow another cockroach and die....

Summarize the given text in a few sentences.
<bot>: Tried to assert dominance over practical jokers by biting a rubber cockroach in half, and it ended up being real.
