So I was sitting at a red light and did a reality check - a real reality check. I questioned so hard if I was dreaming that something scary happened that had never happened to me before. Running off of 3 hours of sleep and it being 9 PM at the time, basically delirious, I had a panic attack. I suddenly did not believe in the world. A shiver of fear ran throughout my body and I just kind of freaked out. I googled what had happened to me when I got home and realized I had experienced a brisk moment of what is called derealization. It's been a few days since this happened and my reality checks have really been incorporating into my dreams more so I'm kind of glad this happened.. Has this ever happened to anyone? What are your thoughts?
