Why do crows follow me?

Although it sounds quite strange, crows seem to follow me. Whenever I go to a park or in to the woods, they literally FOLLOW me! Like, they jump from tree to tree to follow me when I'm walking allong. There are almost always crows in my yard when I arrive home. Also, they frequently wake me up in the middle of the night by caw-ing outside my windows. Oh, and this isn't just recent. This has been happening since I was a baby. I'm not crazy, because I know you think I'm hallucinating. Other people comment on this too like my mum, uncle, grandparents and friends. I haven't done anything bad in my life eather. Help!
