'Visions' in the Bible

‘And it shall be in the last days,’ God says,‘That I will pour forth of My Spirit on all mankind;And your sons and your daughters shall prophesy,And your young men shall see visions,And your old men shall dream dreams;

Boasting is necessary, though it is not profitable; but I will go on to visions and revelations of the Lord.

Let no one keep defrauding you of your prize by delighting in self-abasement and the worship of the angels, taking his stand on visions he has seen, inflated without cause by his fleshly mind,
