Sounds like you have some aspect of synaesthesia, but there’s no way to be completely sure about that. Numbers usually come with attached context, which may even be specific to the individual, and can affect how people feel about them whether they have crossed senses or not.

As for me, uh. I like numbers, but I think if I had any feelings about specific ones, practical concerns have long since overridden any of that, so my feelings can’t have been that strong in the first place.

Practical concerns like a preferred number being too quiet or too loud on a volume setting, for example, which people often cite as having to be on certain values with certain properties. Likewise, temperature settings, where that’s even possible to control in the first place.
