I've had a very odd day

It's starting to get very busy for me at work. I was in a 9am meeting and I got a call from my HR manager. I declined the call and emailed her and told her I was in a meeting until 10am but would call her afterword's. She told me she would give me a call. Of course then I spent the next hour wondering why HR was calling me. She finally did call me and it was very awkward. She asked me how it was going and I said good, and then she just came out with it and said she saw that I was on a job board and is concerned I am looking for another job and is there anything they can do to make me more happy so I don't leave. I thought this was very strange, I mean I've been on these job boards pretty much for the last decade I mean everybody is even when they have jobs. It came off a little paranoid to me, I told her yes I go on there but mostly I do as I am helping my son look for a different job right now. I told her I am not unhappy at my job. She said she was glad, then got off the phone with me. About 30 minutes later I get an email from her with my boss cc'd saying that they decided to give me a raise because I am a valuable member of the team and they don't want to lose me. I was shocked to say the least, I am still a little shocked because that wasn't even brought up on our call. We normally only get raises in April. The only thing I can think of is it spooked her so much to see my resume there that they got scared I was actually going to leave. I am not complaining getting a raise when you didn't even think you could or ask for one is pretty nice. It just is weird, and now I am wondering if they expect me to remove myself from these job boards. I don't know just kind of surprised. On top of that I am sick and I almost called out sick because my head is so bad right now. According to my smart watch I got 53 minutes of sleep last night. So I guess I am just wondering if I am still dreaming.
