If you just like how something looks, that's fine, but there's a difference between "I like how X looks" (subjective opinion) than "X helps me sleep better" (difficult to prove but objectively true or false).

Yes, of course I’m going to be suspicious.
Gaslighting doesn’t exist, you made that up because you’re fucking crazy.
