Toddler becoming afraid of the dark?

My son is only 22 months but the last week or so he’s been screaming at bedtime. I thought maybe a regression or teething. I started turning on his monitors night light and that seemed to help for a bit.

But tonight he woke up around 11pm and it’s now almost 1am and he will not sleep. When I go in his room and pick him up he clings to me for dear life and stuffs his face in my neck. Then while rocking him he would pick his head up and look around the room slowly in every corner. And when I try to lay him down he immediately starts screaming.

Does this sound like he’s developing a fear of the dark? I hate he can’t communicate what’s wrong and it’s scaring me 😫
