A sign to the unbelieving
1 Corinthians 14:20 Brethren, be not children in mind: yet in malice be ye babes, but in mind be men. 21 In the law it is written, By men of strange tongues and by the lips of strangers will I speak unto this people; and not even thus will they hear me, saith the Lord. 22 Wherefore tongues are for a sign, not to them that believe, but to the unbelieving: but prophesying is for a sign, not to the unbelieving, but to them that believe.
We are seeing a lot of "signs to the unbelieving" these days. The Lord is merciful, He is filling the airwaves with warnings. These dreams and visions are merciful, it is helping these believers to speak for the Lord. When you speak for the Lord you are a "prophet". Prophets do not simply "predict", rather they are like a press secretary for the President. They speak for the Lord. If you are a fully functioning believer you will be speaking for the Lord. There are many gifts, many operations of the gifts, but in every case they are speaking gifts. You don't have to be a preacher or teacher to speak for the Lord.
Also you may not be gifted at something, but you still need to do it. We do not leave all math to those with Phds. Everyone has to be able to do some math, in the same way everyone needs to do some preaching and teaching. You don't need angel visitations to speak for the Lord. The New Testament records several angel visitations, so that is certainly one possible experience, but it also records many other experiences of the Lord without any angel visitation.
When you speak pray first.
24 But if all prophesy, and there come in one unbelieving or unlearned, he is reproved by all, he is judged by all; 25 the secrets of his heart are made manifest; and so he will fall down on his face and worship God, declaring that God is among you indeed.
Pray that the words would come from the Lord and touch people's hearts. That they would be reproved and judged by the words the Lord speaks through you. Pray that the secrets of the listener's heart would be made manifest so that they repent and worship God. Pray that those who hear your words would see that God is among you indeed.
