Help me with this petty problem.

[TribbleWithoutaCause]

Forgive me if this sounds silly, but can you tell me the correct way of writing (and spelling) lying in the context of;

'he was lying to her' and 'he was lying down'.

One of these doesn't look right to me and I can't seem to find the answer.

Im almost certain that they are both correct.

Honestly, they are both correct!

They're both correct.

While he was lying there, he decided to continue lying to her.

Yes, both correct.

While he was laid there would be WRONG AND HEINOUS AND STABWORTHY though.

Oh really?! Lord this has been bugging me for ages.

Thank you so much!

Except that the song is right:

If I lay here, if I just lay here, would you lie with me and just forget the world?

Subjunctive and shit.

so should the song be 'if I just lie here'?
