My first lucid dream and my first OBE were simultaneous. You really need to spend time before you sleep mediating on slowing down your breathing and heartrate. Once this state is reached the key to getting out is to maintain the slow breathing and quickly accelerating your heartrate. The cool thing is when you think that it isn't working and you attempt to get out of bed and your foot goes through the floor. My best OBE was simply hearing the most incredible music consisting of stringed instruments and floating towards the source as if I were riding a wave. My entire being was part of the music.
