I trust my subconscious mind, but I want more control to steer the trip where I want it to go so I can hopefully find what it is I am looking for. Due to the ethics of studies I can't just find lab controlled studies and publications explaining how different the 2 substances are, I am mostly restricted to anecdotals such as you saying there is no control, or this outside thread with multiple people saying LSD is easier to control. All I said in the previous post was easier to control, but I never meant to say control was certain.

post 2 and 3 both imply Acid is easier to control

This post uses a pilot and passenger analogy between the two.
That same thread does described shrroms as more mental and LSD as more visual, which makes me lean towards Shrooms more in that regard.
