no vibrations

I ap'd last night. whats weird is i just found myself aware of walking downstairs in the dark. there was no vibrations and pulling out my body, I just realized i was in control. At first i thought it was a lucid dream but after i went outside and yelled something and was responded to, I realized it was an ap. I find this really odd because i thought you had to make an effort when you feel vibrations to ap, this just snuck up on me. After i came back to my body though i did have the vibrations and could have ap'd the normal way, shortly after but I moved my arm and snapped myself out of the trance. I just thought id post it cuz i thought it was weird so thats all ,I didnt know you could shift your awarenss to your astral body without the vibrations, ill be happy to read responses.

It's not uncommon to blink out momentarily and miss the exit. I personally rarely have any vibrations when I project. It's mostly just a gentle shimmering.
