Dream About Jungkook Tattoo And School

I have dreamed that I saw Jungkook the idol but he was younger than now as like I see a video of him when he was younger but the weird thing it wasn't a video I was there too and saw that his left hand had a tattoo but the true thing that he had on his right hand and I remembered exactly where the tattoo initially where and thought to myself that maybe yeah it was his old temporary tatto and it coloured black with writings . I also dreamed that I was at home with my family and I tried two times to got to sleep , I remember the second time I was fr gonna sleep but didn't put my head on the pillow to sleep and also I saw my self solving questions maybe in physics and I heard the teacher saying that I had solved some wrong .
