Yesterday I was so stressed, tired and kinda anxious cause I had a long trip by plane , when I was sleeping I was dreaming about the paper work I had to do on the airport, like Passport, flight papers... And I was dreaming I was not having my passport with me. I was so scared that when I woke up on the middle of the night I was still scared of that, even knowing it was a dream. It took me a couple of minutes to realize that all that was a dream and nothing happened. Is it normal to happen?
