Ghosts?

Im sitting on the couch with my 2.5y waiting for her to finish her milk so we can go to sleep and all of a sudden she stops drinking her milk and says

“Ghost take you away. Take you away. I say bye mommy. Bye mommy!” As she waves

So i ask her her why she is saying bye to me and she says

“Cause ghost wants you. Bye mommy”.

I instantly changed the subject and went to talk to her dad (in our bedroom) about it. And this is after she said someone was in my room earlier today and when i asked her what, she said

“Back and for back and forth”

Her speech isnt the most clear so i asked her what she meant and tried other suggestions and she got on her hands and knees and said

“Back and forth, back and forth”

This is not a joke and its really freaking me out. This is not the first time she has said stuff like this but this is probably the most descriptive.

We have lived in the same place for 2 years and she doesnt watch anything scary. Her screen time is limited to dora the explorer, paw patrol, and little kid shows like that.

Has anyone had any similar experiences? Did your child outgrow it? If so when? Im hoping its some sort of a weird phase.
