Not snakes, but definitely reptiles like iguanas and lizards! Ever since I got really into LSD I have had a really deep connection with them, for some reason. Oddly enough, the two other biggest LSD users I know all are super into lizards as well. One has what amounts to basically a reptile zoo in his living room, and the other has a pet lizard. These two friends also move around in a "reptile-esque" way. Very quick, precise, controlled movements. I always thought it was uncanny. I did a little research and found that reptiles have a significant part in something called the Triune Brain Theory (Link -
Wiki- Triune Brain Theory)
Some relevant passages;
The triune brain consists of the reptilian complex, the paleomammalian complex (limbic system), and the neomammalian complex (neocortex), viewed as structures sequentially added to the forebrain in the course of evolution.
The reptilian complex, also known as the R-complex or "reptilian brain" was the name MacLean gave to the basal ganglia, structures derived from the floor of the forebrain during development. The term derives from the fact that comparative neuroanatomists once believed that the forebrains of reptiles and birds were dominated by these structures. MacLean proposed that the reptilian complex was responsible for species-typical instinctual behaviors involved in aggression, dominance, territoriality, and ritual displays.
the basal ganglia (structures derived from the floor of the forebrain and making up MacLean's reptilian complex) were shown to take up a much smaller portion of the forebrains of reptiles and birds (together called sauropsids) than previously supposed, and to exist in amphibians and fish as well as mammals and sauropsids. Because the basal ganglia are found in the forebrains of all modern vertebrates, they most likely date to the common evolutionary ancestor of the vertebrates, more than 500 million years ago, rather than to the origin of reptiles.
Somebody was speculating that after working with the more complex,usually predominant upper two complexes (not the basal ganglia) following use of entheogens which seem to focus on these, that we temporarily become more aware of the basal ganglia, the one whose functions have no place in intense entheogenic experiences.
So perhaps the behavior of these reptiles remind us about primitive, often recessed aspects of ourselves? Food for thought.
