What the hell? flying spider?

So I walked in my bathroom, and saw what I thought to be was a daddy long leg spider in the top corner of the room on the wall. I let it be assuming it was no harm, but in the mirror, I see it move, and I turn around and it's flying at me. I darted out of there but I swear it was a daddy long leg and it was flying on a mission to get me. I was even juking and putting on my moves to get out of its way but it continued towards me. What the hell was that?
