It was between 2-3 am and i stepped out for a smoke. i rarely leave the porch when u step out to smoke i sit on the bench. well for some reason i stepped off the porch allowing me to see a gravel lot where semis park. i saw what originally i thought was 2 idiots w a engine hoist trying to steal a engine. it was early so it took me a second to realize these figures was at least a ft or 2 taller than the semi hood. they was super skinny, very lanky and had tiny heads. they appeared greenish brown in color although area was lit it was still dark. idk what the bell shapped object was above the engine compartment but appeared to be syphoning possibly clearly just a guess. later i noticed 1 more figure on the other side of the building down on all fours like a "watchdog" there was a craft partially hidden by building. it was your general ufo shape i guess. disk shipped, dull silver w a black window. however this craft looked way to small for these very tall beings to fit in. i remember being oddly calm and i got a little closer. i almost walked over there but decided against it. the last thing i remember after that was i was back on my porch and it was now about 4 am. it was cold out and i just stepped out in shorts and a sweatshirt. i was not shaking cold or anything. and to my knowledge i just went back inside at this point. i obviously have not spoke of this to anyone bc it's insane story that really bothers me bc i know what u saw %100 but it seems so crazy and not possible. i know i'm not crazy but it made me question myself. i promise on my family this is a very true, sober and vivid experience.
