Naletnjak is one kind of Jinn in Bosnia who
possesses the power of transformation. He is very adaptable and he can pass
through the smallest hole or opening. According to folk belief Naletnjak can
be seen during the night if one goes onto a bridge. Naletnjak can jump
onto a human in the form of a cat or a ram in the desire to be carried by the
human or he appears in front of a human in the form of a horse and when the
human mounts him he flies towards the sky, into the clouds, until the call of
the rooster is heard. Frequently the Naletnjak would appear in the form
of a black whirlwind that stretched all the way up to the sky. It was forbidden
to whistle during the night inside a house or a yard since it was considered
that Naletnjak communicated in such a manner and one could call them
when whistling.
