A bat being active during the day and colliding with you is very abnormal behavior. If rabies exists where you are (this includes the UK for bats) see a doctor ASAP. Like, I wouldn’t go to bed without doing it. It’s possible for you to be bitten without feeling it because of how small they are, and disorientation is a sign of rabies in bats.

It’s totally fixable even if it did have rabies and bite you, you just have to go get a (normal, NOT in the stomach) post-exposure shot.
