It was awhile ago but I think mostly I would just try to keep my mind clear and focus on the mindspace area behind my closed eyes. The projection was spontaneous and I could only get my astral arm out. Most of my projections occur when I am asleep and will spontaneously become concious...I will feel myself float out of my body but I will have no sight. I know meditating in bed isn't the best because we are programmed to goto sleep there. I've been trying in a chair lately.
