Why were a bee and a wasp both in my bedroom?

I got home from work tonight, lay down in bed, and was promptly stung by a large bumblebee on my leg that had been in my bed (under the blanket it seems).

It was scary, but once it had been removed from the apartment I figured, what are the odds of this happening again? So after a while I shook out my blanket and, feeling a bit freaked out, lay back down in bed.

Then I saw a wasp on my ceiling by my light fixture. At that point I freaked out and left the room.

Luckily, one of my roommates is away for a few days so I have a room to hide out in for the night but how could this have happened? Bumblebees and wasps are different types of insects, so is this just a coincidence?

Some details that may or may not be relevant:
I live in rural Massachusetts
I live in a basement apartment—the windows are ground level.
my window was closed.
I hadn’t slept at home the night before, but I /had/ left a half finished hard cider on my windowsill by mistake from the night before that.
the wasp seems to like sitting on the fan by my bed.
I went on a long bike ride today on my way home—I don’t think any insects attached themselves to me, but I guess you never know?

Anyway, if anyone can put my mind at ease (or not at ease) as to why this happened (/help me feel safe in my room again) I’d appreciate it greatly, thanks!
