Imagine it as a soft reset for your brain, it's the best way I can describe it.
Ibogaine technically is not a psychedelic but an '"oneirogen", which means "dream inducing". The trip comes in stages, but at the peak, some enter a state where deep lucid dreams can be acheived by merely closing one's eyes and out of it just by opening one's eyes if it gets too intense; with common trip reports of people physically coexisting with their deceased family and literal demons, as was my case.
There's also the notion that it aids in unlocking memories. In my experience, it did though they appeared to be inconsequential ones from my toddler years.
The morning following the experience, I bit into an apple, and it tasted as if it were the first apple I'd tasted in my life: my senses appeared to have undergone a literal reset. This might explain why many people turn to it as a means of overcoming opioid dependence.
It is a deep deep rabbit-hole and I can't do it justice here, there's a whole religion based on it in Gabon Africa.
