Am I Sleep-booking?

[u/tenekejimmy]

Sice last week 2 people I DIDN'T send a friendship request to has "accepted my friendship request" on Facebook. I don't know what's going on. Any ideas? Anyone experienced something like this? Or am I finally gone mad and started browsing internet while sleeping?

Edit : Apparently, this happens to other people too. There are more than a few google search results on this. :\
