Hairs on pillow in the morning? (Photos)

Hello all. I never really paid attention to my hair before. I usually shower every 3 days. 1 and 2 day I don't shed much but on the third day in the mornings I have at least 20 hairs on my pillow and if I rub my hair over a sink a lot fall out. Is this normal? Also is it normal for hairline to be see through in bright bright light such as the sun? I have added some pictures for evaluation maybe I have BDD I don't know. Thank you everyone for your time
