I dont think that Astral Projection Is dangerous, especially If you not afraid, overcome fear. And I dont thing or heard that anyone couldnt return or was stuck. When you Astral Project you consciously leave your psychical body and travel with your Astral body and there Is a connection between them wich will likely break after death. It Is a good thing that you are naturaly more spiritual, talended with this stuff. However not everyone believes in Astral Projection/OOBE, but Its real. Its very useful. You can find many answers there, experience trully great stuff. If you want to find more about this spiritscience.net | Science Spirit
Dont be scared, Its awesome! My friend have even seen his future, met with his higherselfs and changed his view of life in way better way! In my opinion when we all die we will be detached from our psychical bodes(silver cord breaks) and we will experience something very simialr to Astral Projection and It would be a good thing to be a little experienced with this stuff, to be prepared for life after death
