I dunno, personally DMT and mushrooms are near identical to me..has she tried oral DMT or ayahuasca? I would bet that if psilocin was vapable she would feel the same way about it as she does DMT. DMT and mushrooms have more in common than LSD has with either of them. I cant see anyone who likes mushrooms not enjoying oral DMT once they find the approriate dosage for them, which is different for each individual.
My point being, that I would bet that her dislike of DMT has more to do with route of administration than it does with the DMT experience itself. Smoking DMT can be very disphoric due to the rapid onset of effects, it is somewhat difficult to settle into a vaped DMT experience compared to an oral dose. I personally find mushrooms to basically be an oral DMT trip.
In reguards to LSD, neither is closer to LSD than the other IMO. DMT is far more like mushrooms than LSD is, though I havent taken acid in a few years so..
Long live the unwoke.
