He didn't smile or anything - just stared blankly into my eyes. I was really caught off guard, I didn't know what to do.
This has happened on numerous occasions with the same guy. He knows who I am just never says anything.
What could it mean?

It's a blank stare. It means nothing.
If he hated you, it would not be a blank stare. He'd be looking daggers at you. Or sneering.
You just want to assign some emotion to him, because you don't like the thought that he could look right through you as if you didn't even exist at all.1
