She felt hyperconscious of her surroundings during the presentation, noticing every little detail.
Hyperconscious → It is formed from "hyper-" (from Greek "hyper", meaning over or beyond) and "conscious" (from Latin "conscire", meaning to be aware). The word "hyperconscious" refers to a state of being excessively aware or having heightened consciousness.
Think of being 'beyond' ('hyper-') just being aware ('conscious') — that's why hyperconscious means having an excessive awareness.
