I would not listen to anyone. Everyone's trip is unique unto themselves. Shrooms are a conversation between you and your soul/the universe. Think about where you would feel most comfortable to have this conversation.

For me, it was in a quite dark room with my eyes closed. Also, direct your experience and try to remember that life and death are illusions. Strip yourself of fear and you will become whole.

Happy trails. If this is your first time, perhaps a heroic dose is ill advised. I would start with a gram.
