my first ever ghost experience

A little backstory.. when i was around 10 or so maybe a lil younger, me and my fam moved into this apartment complex and ive made some friends around my age in the same area. One day they told me that allegedly, a man died in the very same apartment, obviously i was a shaken by this but a little part of me was interested with that information... Now fast forward some time after i was done putting my clothes on some hangers and as i went to hang it in the walk in closet, i turned around and for a split second i saw a really tall man that had no head, an off-white almost yellow t shirt and black rugged pants, that disappeared really fast. I got really startled by this and i stood there frozen for a couple seconds, i quickly got out of my room, into the living room with the rest of my brothers and tried to act like nothing ever happened... 

As this was my first "experience", its pretty anticlimactic and generic, but i do wanna say it supported the theory of something was in that apartment with the following events that happened after. I've lived in there for at least 2 years and i have a handful of other stories that me and my family experienced
