Personally, I never wake up with vibes. In fact, I would say 99.9% of my projections never experience any sort of detectable shaking vibration.
On the contrary, when I'm about to project, my body gets extremely numb. It's a little tough to describe, but when I feel that way, I imagine my arm start to melt into the ground. Once I feel that "melting" sensation, I know that my astral arm is in fact out of my physical body. I then exert a little effort and separate completely from the body.
I only say this because not everyone will experience vibrations, so don't try and focus on them too much. In my opinion, many people look for these vibrations, and then they get discouraged when they don't experience them, or think that they are not making progress.
