Guy's Behavior

Creepy professor or is it just in my head?

My friend, Cath and I were working at a seating area in a college building where there are always people sitting together, sharing charging ports. I remember we were sitting with this group of students who we didn't know. A few professors were nearby as well. This one professor came over and requested to use a charging port and since someone in the group had one available, he sat down to charge his phone. I actually knew who he was, I took an "explaining the major" seminar with him when I toured the campus in High School. Regardless, he is a professor with many people to talk to on a day-to-day basis so I doubt he remembered me. To continue: when he was sitting in our seating area he was talking to a few of the students near Cath and I, however, we didn't talk to him and weren't paying attention since we were working/helping each other out on assignments. I was looking at my computer, but I could still see out of the corner of my eye, clear as day, that every now and then he was staring at me. I thought it a bit odd, but he was right across from me and who knows, maybe he was just lost in though. I wasn't looking at him so there was certainly no reason for him to be doing it because I was doing it (that sorta thing). I brushed it off. Eventually, Cath and I decided to head out. As we were packing everything up he was again, staring at me. I was leaving, so of course, I was drawing attention to myself, and I once again, brushed it aside. What really got me, was that when I was walking past him, leaving and looking back to check if I'd forgotten anything, I glanced over and he just locked eyes with me before I walked on. At this point, he had turned his head to look at me. It wasn't so easy to brush off because at this point, he had gone out of his way to look at me. Overall, does anyone else think this is creepy? Is it just in my head? Should I exercise caution and avoid any classes with him in the future? Honest answers, please! :)
