I just saw a video and am afraid of being hypnotized!?

Hello! I just saw this video on youtube. Now, I was researching aliens and I clicked on this link and it was a head spinning in circles with like a circle in the back and saying "Kill yourself" very fast. The narrator said you will have dreams from this. I am petrified! I saw this video for 5 seconds, is that enough to seduce me??? I am terrified.
