I can relate too. In my teens to mid twenties I had quite a hefty eating disorder. Sometimes I would feel so thin - skinny even. Other times I would feel absolutely huge. A waddling obese whale. What I saw in the mirror corresponded with how I felt about myself. I always thought that was weird. How could I look so thin in the morning, but be obese by lunchtime!

So one day I thought I would see if I could 'make' it happen in the mirror as I watched. I was feeling thin, looked in the mirror, and saw thin me. I stared at me and concentrated on trying to feel obese, and sure enough, the me in the mirror started 'morphing' from thin me to obese me. It *really* freaked me out so I didn't try it for long!

Since then Ive had similar experiences, but more along an age spectrum than a size spectrum. I can be fresh faced pure skin me, all the way through to a massively wrinked, grey and sallow skinned old me.
