After a few worried communications about my mental state / consumption of mind-altering narcotics (and a very concerned conversation with my mother) I can reassure all my readers I am not on acid or having some sort of delusional breakdown.
A haiku is simply a Japanese poem. And the 'monstrous psychedelic bubble exploding in my mind' is actually the name of an album I've been listening to.
Glad to have cleared that up. Normal drug-fuelled madness will be resumed shortly.
