Woke up very anxious

I woke up this morning feeling very anxious. I am not sure what is going on. My heart is pounding, I am very shaky, and I just feel super anxious.
I told my mom about how I was feeling, something I rarely do. She said I must have been dreaming about something and it made me feel anxious. I’m not sure, I cant remember what I was dreaming about last night.
I woke up at 6 AM this morning, I do remember I woke very suddenly. Mom was getting up then so I got up too.
Its 8 AM now and the anxiety hasnt gone away yet. I hope it will go soon.
