ship dreams

right, so i was in a ship, on the top deck and there were lots of other teenagers around, we were supposed to be swimming on the ocean. the ship was tilting but somehow it was ok, then me and my cousin was diving to the ocean. when i went in the water, its like i didnt even go down, i was somehow floating (there were also other kids in the ocean swimming) then when we came back to the ship, we went to this island and your not allowed to go in the island unless you have a cycling or driving license which i dont have but i somehow got to the island anyway, then i was spraying water with sand to these birds on cages because they were supposed to be evil or something, they dont have powers but they attack humans.. then after that, i was riding a horse and it was leaping a bit too high, when its going down i remember feeling scared and i could feel it when we reach the ground. then we went on top of this castle where the other teenagers was waiting for me and my horse then theres this little flying thing like a helicopter and it was shooting us pins that can make you sleep.
when i woke up (from the pins) we were all in this big room and were removing the pins from our body (pins that you use for sewing) mainly our necks, then theres this person in white and i just somehow know that she was the helicopter earlier. then she told the right line to stand up coz she was gonna heal them then they all had this yellow light around them, then it the left line which i was in and we all were in this yellow light as well but then after the light was gone there was still this pin from my neck. (the girl punished us for going on top of the castle, i think)
after that were somehow inside the castle and i was running away from this man with guns coz he wants to kill us so then i was running then i ended up on this place where all the other teenagers was having lunch there was a red and white stripe over us to cover from the sun and i was telling them to run, i just kept on running but then i heard lots of gunshots then i kneeling on the floor beside this gallon-big-jugs of water, then i think the other people was thinking that it was my fault for bringing the guy to that place but then i was mixing water with this white liquid, im not sure but i think its milk and then i was blessing it with my hands and it is somehow going ti be used to bring the kids that was shot back, to heal them...

Other info: my grandma and my other 3 cousins was with me on the boat but not in the island or the castle
