Yes, I did magic mushrooms once about 6 years ago. Now last night I dreamed I was taking it again and I actually had a trip in the dream (though not very long) but I wasn't lucid because it didn't really hit me I was dreaming. I just had the same feeling of increased consciousness in the dream-trip as in the wake-trip years ago. I'm a beginner and I'm still in the practicing recall-/trying to get lucid-phase.
What do you think about the following reflections:

As lucid dreaming has a lot to do with [I]believing[I] that you can have lucid dreams, couldn't it be that my dream-trip was like a method of my own (sub)consciousness to "trick me" in becoming lucid? I said that I wasn't lucid but it could still be a first step in that direction. Well, I hope.
Maybe it was just a "normal dream" like about anything else. And the fact that I took psylocybes once makes it of course more probable that I will dream about it anytime in my life.
