I agree completely with Ayyoshi.
Shortcut to projecting? I heard drugs make you lose control in the astral
And with regards to Ketamine it should definitely not be used to induce an OBE - take it from someone who did do it by accident, you absolutely lose control in the Astral realm, and in a very very big way. My experience really scarred me deeply until I began researching and trying to make sense of it. I'm glad I've stumbled upon this site, I find it quite addictive reading about experiences with our divine source, it's nice to know there are natural ways I can deepen my understanding of the astral realm. I plan to put a lot of what I've read into practice
Also to add onto what Grey Traveller was saying I also think the use of shamanic plants to access the astral realms is a very interesting point of discussion - although I would be pretty scared to try them myself. With regards to hallucinations, I have been having a very interesting discussion on Lycaeum Forums about Datura - a very toxic weed that produces hallucinations that are so real, users are literally unable to tell the difference between the hallucination and reality
Just because the medical field calls it a hallucination doesn't mean that's what it is. they call the visions we have in the hypnogogic or hypnopompic hallucinations. i think we are seeing into the astral in those experiences
For example, people on Datura experience exactly the same types of hallucinations - right down to the most incredible detail. I have read about 100 different accounts, and nearly all of them include hallucinatory experiences that simply could not be coincidences. For example most users at some point imagine that they're smoking fake cigarettes which they keep dropping and losing. This occurs even if the person using the Datura doesn't actually smoke in real life. I can't believe scientists don't investigate this. Imagine if we all woke up one morning only to discover that we had all had exactly the same dream the night before!! This is a huge discovery, but the use of the Datura plant is so underground that it hasn't been investigated by experts yet. Some people believe that the spirit of Datura is an evil spirit which was trapped in a plant and that the spirit's power is that it forges multiple realities, meaning that people who ingest the plant seamlessly move from one reality to another - like changing channels on a television (only you don't have the remote). It certainly brings into question the idea that hallucinations should just be dismissed as irrelevant disturbances of the mind. Mankind knows nothing about where they come from, how the brain forms them, and how the narratives are constructed.
I should just say now Datura is an extremely noxious plant, and should NEVER be ingested for any reason. Almost all the people who try it express a sincere regret for doing so. Especially because many of them end up in the ER.
That said...here's my post on the Lycaeum Forum which is being discussed at the moment. A word of warning, it is not for the faint hearted. Also sorry to offend anybody who feels uncomfortable talking about entheogens, but I think they have a legitimate place when discussing hallucinations and the astral.
