These are two different verbs: one means: to be positioned horizontally (lie) and the other to position something else horizontally, to put something down (lay)
They sound similar and have a meaning connected to being horizontal, that's one reason for their confusion.

lie: lay
Yes, Lay is the present tense of one of them and the past of the other: that's the other reason for their confusion!

Referring to the dictionary defenition of a word
Explanation:
This is because the author is using the word in a literal meaning and not in an expressional meaning like a poet does.
Example. The Main Character cannot break through the wall, Its pretty tough.
This is literal. The word " tough " is being used in its dictionary meaning since it means Hard.
Meanwhile a poet might use this as an expression of something else like
" He was heartbroken, the woman he loved had shattered his soul and it was a tough experience for him "
Tough is used as an emotional feeling of being broken down instead of its dictionary counterpart.
