So I've noticed sometimes when I wake up I'll see little reddish areas directly beneath my eyes, almost looks like I got punched in the eyes or something. Has anyone else experienced this?

I'm trying to figure out what the cause could be...I'm incredibly careful about not getting BP into ANY sensitive area around my eyes, and I'm just as careful when I apply moisturizer too. I notice this only happens when I go to sleep and wake up the next day (the redness gradually fades over the course of the day) so I'm wondering if maybe some BP is left on my pillow cases and irritating my eyes while I sleep or something? (I try to to change pillow cases pretty often to keep them clean, but I don't change them daily)

Any ideas on what this could be?
