An extremely controversial subject, and far too subjective from person to person to ever state that 'mushrooms do this' or 'mushrooms do that'.
Mushrooms do many things for different people; and depending on life circumstances, they can actually contribute to negative states of mind; and make your negative aspects even worse.
I know of a case of an introvert friend who took them in a bid to cure his depression; but they only turned him further in to himself, and some would say made him worse.
The results really are subjective from person to person. I am all for their use and the experimentation with them to see how they work for you and what insight they bring; but I definitely think they should come with a warning.
False hope can lead to dodgy things, and if you put all your eggs in one basket, just be prepared for that basket to fall from a great height at some point. It makes the shockwaves a little easier to absorb when you realise it's not all rainbows and fairies.
