Is it normal that i dress like this at home when i'm off from work?

When it's my day off, I like to wear clothes that I obviously can't wear at work. I want them to be as comfortable as possible, so I don't care how they look, just as long as they literally feel good covering my body. If the clothes happen to look good, then that's just a bonus, but I just need to be able to be pick something quick and b comfortable and also literally wear it how I want. The problem is I can't wear what I want at work or even how I want to because it's considered unprofessional. But it's ok, because at home, it's a safe place. Here's an example of what I wear so that you know what I mean:

It's really great. I feel so bundled up, snug, and warm to have my body wrapped up this way. When I'm at work, I can't wait to get home and dress myself this way. Even my mom asks me if I'm comfortable, so I say yes and she says that's good and that I should keep on wearing them that way then.
