The first steps into magical practice tend to involve a period indistinguishable from an acute bout of mental illness as the mind tries to get used to its new surroundings and ascribing a new and unknown value set to things it long before became conditioned to reflexively reject.
However, some practitioners stop in that place and don't advance or push past it. It's very important to exhaust your impulse to take this period seriously, it needs to be pushed past and it must be integrated into a resumed functioning in the mundane world without losing yourself to either. Otherwise the risk is simply too high that practices will exacerbate neurosis.
So, no, that /pol/ thread was not quite right. Rather, it's characteristic of someone who is just starting and should cart and deepen their practice a bit.
