Its hard to explain Datura... really is since it connects you to world that are normally unseen.
In some worlds you feel lighter, in others very heavy, but always very heavy in the physical plane. This gives me a strong root for this kind of voyage in the mind, since I do not really enjoy just going around for fun, the responsibility to psychonautism I have been talking about... The desert throat and the heavy limbs leave when you are able to accept that you have less control upon what you are going to see. If you resist you will be pushed and pulled towards violent hallucinations which can even feel painful, and your will "burn and dry up" you will want to throw up. But if on the contrary you pay attention, and you are minded to accept that the characters in your lucid dream ought to be free, even if what they tell you is not pleasant... then you will enter that watery space where everything seems covered in jello. This is also common with the high dose amanita, they bring you to the same place, exept that for Datura, the plant consciousness is there like a cat thats really itching for a hunt. If you manage to tame and calm her then she will be gentle, but merely juggling with ego dynamics might get her too much gentle, so much that you might feel intimidated by the good feelings she can give you. If you then manage to integrate the first dimentional jumps, and your heart is strong enough to sustain the high heart beat, you will begin to talk to yourself and exit the body so to speak. You might wake up say in your best friends backyard in front of a fire and you light up a joint and the spark from the lighter will wake you up and you realise you havent moved, but 1 second later, you jump back into another space where you have deep philosophical insight thanks for very real discussions with the hallucinations present... or you might fly and see distant spaces !
Thing is it will always be wild, so if you have no good reason to seek its metaphysical influence, you will get whipped and or wipe... it takes extreemly strong willpower and vigilance to handle this kind of trip, or you just fall in deep splumber with some lucid dreaming, which is less interesting for what this plant has to offer. Because it teaches you that at any one moment there is a multitude of archetypes and angels which are influencing your every decision in life, which means you need to have part of your subconscious listening in to those possible presents, so you might learn from them and grow from such insight.
You cannot really associate it with anything as such, because it's very spiritual... maybe a little less than salvia but more stable, it will always seem profound and intelligen, so much that you might not even remember you were on such a substance in the first place. It just gives you the most you can take, while looking very mysterious... You cannot be creative on that because most of the time you are simply paralised in bed, fighting to stay awake, its simply impossible to do anything since your body is on auto-pilot.
