Is it weird that I can feel his (my crush) presence/absence?

I work with my crush and we work in different sides of the building. He's in a different department. I don't know his schede, it changes often and his desk is not in my seeing view. I would have to walk and go look to see if he is there. I notice the past few weeks, I come into work and I can actually feel when he is present at work or absent. Its weird. I've tested out my theory and its worked every time.

Another weird thing is when I'm thinking about him, not long after, he comes and walk past my desk. Today I felt he was no longer at work, he had left for the day but before I left I looked at his desk and thought about him. I go to the gas station near my job and he's there driving out, as I'm driving in. Weird right? What do you think this mean? Yes, me and him have had small talk and he's nice to me. We don't talk every day but when we do, he initiates the conversation because I'm always too nervous
