Feeling of Dizziness but not really...?

I sometimes get this feeling like I am dizzy but not actually dizzy. It feels like I get tunnel vision like my eyesight gets a little elongated. I feel like my body gets a bit heavier but I can still move and my hearing gets a little muffled. It only happens every so often but not enough for me to go into the doctors for it but wondering if anyone else can help me.
