I need an Unreal Engine specialist

I am trying to build a VR project around dreams in Unreal Engine. I would like it to be around a 4-5 mins experience for users to go through using sequencer. I currently have three levels done, but I need help elevating them and combining them together into a cohesive story. Basically, the experience takes the user on a dream journey, from falling asleep to three different dream stages. Each dream stage will represent a universal dream theme, such as being chased, falling, etc. I wish to reflect these themes in an abstract way and takes users on a journey.
