Just Having a Nightmare About Bugs

Just had a nightmare of my maternal grandma (who is dead already) in which she was in a nursing home. We talked and it was a bit emotional. I forgot what we talked about. Then we hugged and she felt pain. I called for a doctor and the nurse outside came. He shaved her head and there were bugs all over. Started removing them. Then there were more bugs coming from underneath her scalp. He opened her scalp and there were more bigger bugs. There was a big one and the nurse tried to pull it out but her brain with her brain stem got pulled out instead and the big wasp like bug flew around and tried to get me and I woke up with my heart beating fast. The air blowing on me from the fan was too cold and I needed to pee. I still haven't peed now I'm gonna do it now.
