ghost?????

da
My dog wokeup in the middle of the night to pee outside so i let him out and while im outside i see my fiance walking towards me so i make conversation with him .. and the more closely i look the weirder it gets.. it wasent my fiance coming towards me it was a shadow .. and i was wide awake too. After that i couldnt sleep for like 2 hours.. 👀 has it happened to anyone?
