Dream About Finding A Cure In A Galactic Adventure

This dream was about

My dad was dying we were sitting on a couch and somehow I knew he was dying but he wasn't showing any signs that he was dying and to save him my brother and I had to search the galaxy for something but I don't really remember. The galaxy wasn't normal it was a white room with Lego tunnels and each one you went through it was a different world and in one of them we went to this empty room and it had multiple rockets and we had 57 seconds to get on each rocket platform or else it would blast off and someone would be left behind we were able to manage until the 6 one and I fell off and my brother jumped off to save me then we went into a world with inflatable waterslides and one was covered on moldy bunny stickers and to go back to the real world we had to go on it but it was the world's worst waterslide, I don't remember what happened after that but then we were home again and we were too late... I woke up crying.
