I tryed out of body today.. for first 5min didnt feel a thing and then for about 1-2sec i felt so heavy and then i felt like flying... and then OMG!!! OMG!!! i started to see a tunnel... i was so scared... my heart was pounding like insane... this is the tunnel that i saw :
The tunnel is normal for when inducing out of body experiences. Usually you start to hear sounds all around you while in the tunnel and see quite a bit of hypnagogic imagery.
salvia 5x is good too. you want the extract, the leaves themselves are sh**. it will give you visuals, not only the feeling but the reality of traveling thru a tunnel. total loss of self.. also typical of out of body experiences you will feel a weight on your chest, you will feel like you are about to die. you will feel panic and attempt to fight it. what you mentioned, of "beings" around you.. true that. check out "old hag's syndrome" on wiki.. it accounts for some, but not all, of the phenomena..
leaving your body is an uncomfortable experience, and not one to be taken lightly
