You classify this is normal and rational behaviour?
That depends. I don't think that Theosophists are necessarily crazy, just because of their 'ascended masters' ideas. More broadly, I don't think that everyone who believes that their prayers are answered is crazy. Psychiatry and clinical psychology are careful to make a distinction between healthy religious experience and symptoms of mental illness.
The whole subject of the different ways that religious believers believe that prayers are answered, and precisely how they believe they are in contact with their purported higher powers, is a wonderful source of topics for threads here in the philosophy of religion area of Sciforums. As is the question of how healthy and pathological religious experience might be distinguished. That kind of discussion is what these forums should ideally be about.
My point is that everyone simply throwing school-yard insults and moral condemnations back and forth at each other isn't the best way to explore these fascinating questions. Sciforums needs to raise its game.
Tell me, what is your idea about ascending to the spiritual realm and having psychic experiences with spirits and angels?
The Platonic tradition in the West has historically interpreted our knowledge of logic and mathematics, and our exercise of reason more broadly, in terms of an ascension. Supposedly these things involve our knowing timeless and eternal relationships that hold true in Plato's world of forms, or as later Christian Platonism would have it, in the mind of God. Reason has traditionally been thought of as the divine sense.
And in India the higher meditative attainments are often interpreted in similar ways, as visions of higher transcendental realms.
Ideas of visionary ascensions to higher realms are actually quite common in the history of human ideas and examples can be found in just about every culture known, all the way back to prehistoric shamanism.
As far as ghosts, spirits, angels, gods, goddesses and God go, I don't believe in their actual existence. But I am very interested in how people who do believe in higher personal powers imagine that these purported beings interact with human beings like themselves.
I'm not entirely sure what to make of all of this stuff. Personally, I tend toward a stoutly physicalistic view of things. But I definitely retain an interest in these older and more traditional interpretations of reality and while I think that their literal truth is unlikely, I'm not as willing as some here on Sciforums to ridicule them as nothing more than bullshit. At the very least, they reveal very interesting things about the deeper levels of human psychology. I don't for a moment want to label everyone who holds these kind of beliefs as crazy.
