Strange? As opposed to what, familiar? Physical? As opposed to what, mental? Relax, everything will be all right.
"strange" as in doesn't follow intuition or common sense. Like, if your mother took a fast ride, she could come back and be younger than you are. One of my favorite remarks about physicists is that the closer they look, the more the stuff they are looking at disappears. Or, that what we think of as "solid" stuff is about 99.999999999999999% empty. (I guessed at the number of trailing nines there, but it's in the right neighborhood).
Agreed, thing will turn out fine. I read physics just because I find it interesting. I like music too.
