I’ve tried this technique and I’ve advanced a lot. 
When I looked at my eyebrows with my eyes closed I started to feel weightless, so I began to focus on my body feelings. Then I started to feel like I was swimming in the air. 
I was so tired that I fell asleep afterwards. 
And when I woke up the first thing I did was to write my “trick” in my DJ. 
I have to say that this technique is the best I’ve tried for a beginner like me.
