Mystical experiences

I find an article on the web that describes some features of the peak, or "altered state" experiences I have had (e.g. here). I start understanding the universality of my own experiences, that these experiences are, simply, what is commonly referred to as "mystical experiences".

It feels really good reading articles like this one, makes me feel less lonely: there are still not many people around me with whom I can share about these things (which is why I am searching the net in the first place). I often feel "crazy" sometimes... The article says:

"The intensity of the experience seems to be measured by the way in which the individual's life is affected. No matter whether the experience is great or small, the life seems to be altered or reshaped some way by it; and, perhaps this itself is the mystical quality."
