Floating red light

It was a red tiny light that had jellyfish tentacles looking legs hanging from it . It was snooping around next door at a car wash then it flew my direction & went above my apartment building which is not very tall . Once it came closer to me & I believe this thing acknowledged me standing there in shock . That's when it went from a tiny red looking jellyfish to a big bright light like a star & literally disappeared in front of my eyes . I stood still the entire time because I was afraid but once i realized it was gone I ran inside & its been on my mind ever since . I have a short video on my phone but it doesn't do me any justice all you can see is a red light but barely.
