Welcome to LD4all wezeltje 
(You could introduce yourself inThe Big “Hi I’m new here” topic if you want too)
Besides the spinning around method that you already mentioned, you could try to think of a door. (You can also use a door which is already somewhere in your dreamscape.) Imagine a whole different dreamscape behind it, the dreamscape you want to be in. Instead of using a door you could also use a mirror. You could even use a wall to walk trough 
Another method would be flying to another dreamscape. You say flying is more like jumping very high for you. So you could jump very high on a way you can’t see any details in your dreamscape anymore. When you fall back to land, you imagine the dreamscape will be different.
If you want to wake up, you could close your eyes and say to yourself you will wake up when you open them. Just make sure it’s not a FA where you end up in. I also heard from someone that when she shook her head hard she would wake up too.
