Be careful to distinguish between glossolalia and visions/dreams. No one I've met yet has claimed that Pentecost was the fulfillment of Joel 2:28, as within context, that makes no sense whatsoever.
Peter seems to believe it is the fulfillment of Joel 2;
(Act 2:14) But Peter, standing up with the eleven, lifted up his voice, and said unto them, Ye men of Judaea, and all
ye that dwell at Jerusalem, be this known unto you, and hearken to my words:
(Act 2:15) For these are not drunken, as ye suppose, seeing it is
but the third hour of the day.
(Act 2:16) But this is that which was spoken by the prophet Joel;
(Act 2:17) And it shall come to pass in the last days, saith God, I will pour out of my Spirit upon all flesh: and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams:
As for the gifts, I recognize the difference but there is a definite connection in how the gifts are abused and how mysticism influences.
