What does this dream mean?

I had a dream that I went in a spaceship and discovered a planet that had water and tiny aliens and they shrunk me to their size and sent me on q " mission" and in that mission I went In a cave that I was skatEboarding through with a group of skateboarding guys and we were being led by a woman Alien And water started to come in the cave but it looked like as if it was being lite up by lighting and it was very bright. And all of a sudden A painting that I had apparently painted ended up in my hand and I telaported back to where I met the aliens to leave my painting so It could be easier to walk through the cave and then the alien women who was leading us said that she couldnt go on from there and she left us to continue the mission. Also in the dream one of the guys who were skateboarding in the group kept looking at me and it felt like he was new to the group. Sorry if that was really confusing but I couldn't find anything to interpret it so easily. PleAse tell me what this could mean thankyouuu :)
