First Salvia Divinorum experience

To start with I should inform anyone who doesn't know salvia is active in the micrograms. You don't need much for a break through experience. Anyway I loaded a cigarette pipe full. I prepared myself outside facing south and ignited the bowl, inhaled the whole smoke and held it in.....1......2.......3.......4.......5 bammm. Everything starting too rotate too the left I remember hearing myself say holy shit!!.Next thing I see is a bright rainbow color emitting from the pipe in my hand. Im in the cosmos riding on what appears to be a bus or train that felt like every soul that was aboard was along for the ride or trip. We began to go thru a wheel of realitys starting from the feet up. I could hear and feel each reality as they revolved. At that point I was done and wanted back too our reality and remember seeing our reality and jumped back in. I immediately got up and started moving around. Mother salvia always gives you the option. I now know not to fight anything and too just let it happen mind you I was by myself with no guide. Im pretty strong minded maybe those are characteristics of a shaman.
