I'm aware that imperative and interrogative constructions can take no subject as it's usually implied ("Look this way!!", or "Why look that way?"), but what about an indicative sentence like this one:
Running through the hallways frantically shoving food down my throat wondering if anyone nearby notices, stopping for a moment to say hello to the principal while wiping food from my mouth, realizing also my shirt was untucked, tucking it in, proceeding through the hall, down the stairs, out the door to the bus.
I've noticed these kinds of sentences in avant-garde literature, especially fiction, and was wondering if it's technically grammatically correct, or if these authors are slightly bending the rules.
I'm just realized that perhaps it could be considered an adverbial clause and thus not an indicative... but if that's the case then there's no verb it's modifying and therefore left dangling... Any thoughts??
