quick question
Did you get forced to click the video in the dream or did you decide to click it in the dream?
If you got forced to click it (as in the dream did it without you thinking anything) Then its a nightmare.
If you chose to click it, well then your lucid dreaming. If you dont know a lucid dream is where you know your dreaming so you get to control the dream. Its very rare to happen but it happens mostly when your a child 2-14 yrs. if it is keep trying to get that dream to come back as soon after youll be able to make your self fly and summon skittles and rainbows in any ordinary dream.
Hope it helps.
