One of the biggest advantages of using fungi for manifesting these experiences is that no matter how harrowing or overwhelming an unexpectedly-intense trip may be, you WILL survive and come back down from it (assuming you're not tripping in a physically dangerous setting or something not directly related to the mushrooms themselves).
If things get too wild, and emotions run rampant, this should be remembered and any rash decisions in the heat of an emotional moment need to be staved off. Like Sidestreet mentioned as well, if you decide to ask someone close to accompany your trip that doesn't mean they need to be present in the same room, just nearby enough to where if you needed the presence of someone to speak to to help channel the emotions in a constructive way then you have the opportunity to do that.
