Woolyman I've had similar experiences but with out drugs. The feeling of euphoria was more than my body could handle I started to see others and remember things briefly. I could have bottled that feeling and gave it away. It occurred when my physical body was weak. I had to lay down. I think I crossed over a bit. But few and far between experiences. I'm still here. Waiting for more. In the mean time I am learning to hear and see Him because our Father truly fills the world .Just like you said put on your spiritual eyes and ears. Kathy
