This morning, i astral projected. After coming back to full body awareness, i had a hot shower. I dried myself off and then laid down on my bed.. I noticed that i had obtained strange symbols or a mark on my arm in the shape of an 'x' or a triangle or lines.. I could not make it out properly, but at the first glance, it was an 'x'.... Does anyone have any possible answers as to why this may be?..
