Have I achieved the 'right' ending?

Look, I'm going insane. I've become a great one... Oh my god... I've become an infant great one...

I turned into a slug!

Do you see that thing in my girlfriend's hands? That's me! I was really hoping after I killed Gehrman I could have her for myself, but... Oh god... No! No! The transformation was painful. I resisted the moon presence and turned into a slug - oh, sorry, I meant infant great one.

Have I achieved the 'right' ending in Bloodborne? There's tons of amazing things in the cosmos where I live now, like computers, and I was able to look up what the other endings are. More importantly, I was able to access gaming stack exchange on this cool machine and ask this question.

I feel like the ending I've had is pretty ideal. I've become a slug. I mean, it's not as bad as leaving the dream, it seems like a pretty nice place. Plus, if I left the dream I'd never be able to see the doll again.

What is the 'good' ending in Bloodborne? Out of all the endings, which one is the happiest?
