I’ve seen black figures, never one coming for me though so I can’t say why it would of jumped at you but it’s likely it was trying to throw you off, anytime I’ve seen one they usually try to fuck with me or others in the vicinity, the first time I saw one was at a friends house and he calls me to tell me after I went home (mind you I tried to tell him what I saw when there) that it tried to possess his mom and they had to call a priest, another time I saw one in my living room and it fucked with me for a week, at one point knocking over my cup of water (which my mom saw and choose to ignore, when I asked her If she saw that she pretty much gestured like she did but wasn’t fucking with it lol) turns out it was attached to another one of my friends who told me he intentionally would send out demons to fuck with people but also that for the most part they act on their own will and can fuck with the people around him if he asks or not (he didn’t send this “demon” on me or anything) so maybe it was attached to someone around you or more than likely wanted to fuck with you, if you see any other happening though definitely do a cleansing. I believe in demons but if these figures are actually that I can’t say for sure but I wouldn’t be surprised after my experiences
