Is it normal to enjoy picking and sniffing the corner of my pillow

Since I can remember I have a few unusual comforts that relax me. My first was I enjoyed playing with the seam at the bottom of jeans, I would sit at my dads feet and pick away, I enjoyed putting the thick bit between my fingers!. I also have a strange habit of making my tongue move between my teeth, sounds strange because it's hard to explain!. It basically is like the movement of a baby sucking a dummy except I don't have the dummy. If I'm trying to get to sleep I do this and dribble on my pillow but what's even more weird is I like putting my ear on the dribble!,. I also get comfort from the smell from my pillow, the dirtier the better. When I stared secondary I found a new comfort.. I use to pick the plastic that was in the collar of my shirt, I enjoyed the sound of the plastic bending and cracking and sometimes enjoyed the pain it caused rubbing on my finger. I no longer crave for a shirt but love feather pillows ( only mine). I make the corner really grubby over time but enjoy smelling it. My uncle use to do the sucking the dummy thing and my cousin ( not his daughter) loves playing with soft materials. My daughter loves the corner and smell of her grubby pillow too and sucks her thumb. It must be something that is in my genes seeing three members of my family do it. The only person I have ever seen or heard about is a boy in school who also loved playing with the plastic in the shirt collar.
I have always wanted to find out if there is anyone else who does this or similar. It's hard to explain so I have tried my best without sounding like a freak lol. Can I just add I only do these things in the comfort of my own home and when I'm tired as it helps me sleep.
Please let there be someone who understands me lol. Thanks for reading
