Travelling between dimensions for fun, is there something wrong?

" Hello, everyone. I am the main character of this work. My name is Bai Yimo. I am not human. In short, I don’t even know what species I am. I gave myself the name. In order to integrate into this world, I have existed before the world was born. At that time, species classification did not seem to have begun, so what exactly am I? Cough cough, back to the topic. Today is a certain day in the year 20XX. I don’t know how long I have lived. It happened this morning. I just woke up from my comfortable bed. To be precise, I was woken up by something called dimensional chat in my mind. I’ve lived for so long and I’ve never seen it before! However, the people there speak very well. I really like this exchange.”
