Can't I say just "I woke" instead of "I awoke"?
Great question. In English we have "wake", "awake" and "awaken" as three different verbs with very similar meanings. There past tense forms are "woke" "awoke" and "awakened." Ex: I woke up and immediately checked my phone. 예: I awoke and immediately checked my phone. 예: I awakened and immediately checked my phone. All three of the above examples basically mean the same thing. However in everyday conversation I would suggest avoiding "awoke" and "awakened". The use of awoke or awakened sounds a little old-fashioned or poetic. Which is why it is used here as the movie is set in the past.
