I woke up in the middle of the night feeling really disoriented which lead to a panic attack, I slept through it and I've felt weird ever since. The next few weeks I felt like I was trapped in my own mind and it made me really anxious and nervous. I usually ponder about thoughts that life is a simulation, nothing is real, I'm dead, etc. My memories feel like they never happened or they were just dreams, these feelings usually peak up during night and I've lost a lot of sleep due to it. I don't know what this but I feel like I need reassurance that everything will be fine.
