What do I do?

Have you asked her if she is having a bad dream maybe?

Are you able to take her to pee? Does she seem to calm after?

What conversations have you had with her the next day about it?

Does she have a night light?

Does she seem to remember the next morning of what has happened at night? If not, she might be having “night terrors”.
Often happens when kids get overly tired and stimulated throughout the day. My 3 year old had them a few times. He would scream/cry very loud. There’s not much you can do other than just sit and hold them- once I tried to wet his face with some water and that seemed to help a little and cause the crying to subside. He’d then go back to sleep, next morning I asked him about it and he had no clue what I’m talking about, and my kid typically has insanely good memory

She said she doesn't remember. She also doesn't remember walking to the bathroom and peeing by herself

It doesn't make sense to me because she has excellent memory too. She's already 5 and having night terrors? When does it end?

The only stimulation thing she did really was watch her dad play Pokemon for 10 minutes on his phone. That was 2 hours before sleeping.

I put your question in chat gpt and pretty much got the same answer as what my thoughts were, that it’s night terrors. Here are some screenshots I’m attaching- hope it helps.
