14 month old creeping me out🤣

Okay guys 2 nights ago I heard something in my kids bedroom, I go in there and my 14 month old was laying there laughing, eyes open, just hysterically laughing. She was asleep while doing it too, like she didn’t even know we were in the room until her dad picked her up. And then today I put her down for a nap and she laid there for 10 mins just laughing and she was all by herself. She only knows 5-6 words so it’s not like I can ask her either. Also, for the last 2 nights she’s woke up screaming and when I pick her up she shaking.. but stops as soon as I’m holding her. I do not know if this is normal, pls help🥺
