I looked into the backyard and noticed a round flying disc in the night with different color lights that appeared to shine towards me

I know this was something that could not easily be explained... I knew for sure that it was not a helicopter or an airplane or a star or planet. I have seen ufos before and also while I was with my family a few times, so its not just myself who has experiencing this. My Mom also saw this ufo. The ufo that I saw yesterday seemed to cloak itself off an on. It emitted different color lights that seemed to be directed towards me even from so far away. I went to get my phone camera to capture this thing. It was very unsettling but I managed to capture over 4 minutes of video. I am still scared and find it hard to relax or sleep. I have been looking to move out by myself since I am tired of living with my parents... but now I am very hesitant because I am worried that I am not safe.
