Concept:The speaker is Nick Bottom, and his strange condition is part of Oberon’s plan.
Explanation:These lines are spoken by Bottom after he wakes from his dream.
He vaguely remembers being loved by Titania while his head was changed into an ass’s head.
This situation was deliberately arranged by Oberon, the Fairy King.

Thus, Oberon is the architect of the speaker’s current state.
