At first i thought someone was out flying a small plane with a red light on it at dusk, which made no sense in retrospect. i went in to get my phone and when i came back, this giant red orb as big as mars or the sun (there are pics of this online) was as if it was waiting for me, hanging perfectly in the sky and framed perfect by the doorway. the pics i took of it do not capture what i was actually seeing. what i was seeing was much larger and deep red. i was standing in an open doorway facing north when this appeared. after it floated away and then seemingly blew out, i became violently ill after around 30 minutes. i stayed ill and felt flu like the next day. i also had a sense of dread related to it's possible return (which it did not). interesting but scary and from another dimension for sure. not a plane, not radar, not a balloon, not a drone or anything like that. intelligent.
