More than a month ago I had a strange experience and had hard time figuring out if it was actually real or just a dream. I woke up at 4 am and saw something on the ground. When I raised my head, I realized it was a bat, and just at that moment it attacked my hand (although I can't recall feeling any pain) and flew out directly through a half-opened window. I was sleepy and it took me a while to realize what happened, I'm not sure if I woke up at that time or not. After that I just went back to sleep. Even when this course of action seems pretty unlikely, how much it seemed real (the windows were opened as I left them, and I rarely open them; I woke up from the same position as I went to sleep and even the amount of sunlight in my room was the same as when I woke up) makes me quite worried. When I woke up the second time, there was only one ’fresh’ wound right next to my nail which looked like a hangnail wound, and it could easily be there before. There are a lot of bats flying around our house at night, so I'm not sure if I should get vaccinated because of this event or not, therefore I'm asking for your advice.
