Me And My Husband Used To Meth Around Quite Frequently

Me and my husband used to meth around quite frequently we are in recovery..but my question is while we were high my husband would say that I got taller I thought he was crazy until one day I stood next him (and normally my head would lay perfectly on his chest with his head on top of mine ) I was eye level to him.i want to know why or what could make us both see this change?? Thank you
