I’m a weirdo who vaguely enjoys my MRIs. I’m moderately claustrophobic, but they still don’t really bother me. And I love the warming feeling that makes me feel like I’m getting microwaved.

What warming feeling? An MRI shouldn't really make you feel warm unless they're pushing IV contrast.

My understanding was that your body was absorbing some amount of whatever electromagnetic stuff passes through you for the image. And the techs have told me it’s nothing to worry about.
