We are inherent acquirers of knowledge, primarily tutored by other learners who themselves were also taught by others before us, tracing back to the inception of life and the universe. The physical bodies we inhabit are renewable; the most crucial component is the learning process itself. This is classically referred to as the "spirit," and it can be channeled, like mimicking someone's voice and mannerisms or being conscious of their influence within us (i.e., recollecting what someone is like).
Those who fail to grasp this fundamental concept are the ones deficient in understanding. In your situation, the individuals around you are affected by negative spirits influenced by pharmaceutical profits, such as the demonic spirit of greed, and this basic spiritual understanding doesn't align with their goals. Hence, they have expended an abundance of resources manipulating public opinion against anything that doesn't maximize their profit, using predominantly negative spirits that are unreal. This was not their original idea. It originates from a long series of governing structures like monarchies, dictatorships, lords, corrupt religious bodies, etc., which have evolved in unique ways in the contemporary world.

It sounds like you were being stalked by the greed demon, which portrayed itself through your brother, your therapist, and others in your surroundings. After you freed yourself, the demon desired your return.
Psilocybin exposed the truth to you. The truth is not readily accepted by those who don't abide by it, which is why solutions involving drugs are often discouraged in most religious practices. Recognize that the people around you aren't living in reality. Refrain from engaging in discussions or quarrels with them about it. They aren't to blame. You can help purify them, but be aware they may confront the same issues you did.
Re-integrate into your environment by following societal expectations, but retain the wisdom you acquired. There's no need for excessive efforts. You may also return to pharmaceutical drugs during this period. Once you have re-established yourself reasonably, seek out the following communities and abandon the pharmaceutical drugs if you've resumed:
- A church or a mosque
- A Vipassana retreat and corresponding community
- Other Buddhist communities, Tibetan, Zen, or Thai also provide excellent platforms.
- Tantra community
- Mediums and witches
- Alternative therapists
These communities comprise individuals at varying stages of understanding, so don't be overly expressive. Only share your understanding when it is appropriate to do so. Safely, you can initiate discussion ONLY when someone else does, and don't contribute excessively. Over time, you will surround yourself with higher spirits and be more capable of dealing with negative spirits.
