Hey, dropping in to say, in response to lay (on your review for starliteevee's Drowning):
Yes, the way she wrote it is correct. The past tense of "lie" (as in, the action you take yourself to place yourself in a reclining position) is actually "lay." "Laid" is the past tense of a related verb, "lay" (the action someone else takes to place you in a reclining position). So you can only use "laid" if it has an object, but if you mean to say that the subject was the one lying down, you can only use "lay." It's strange, but confusing the two is a common mistake writers make.
