There's a helpful book on discernment of such experiences, aka testing the spirits.
It is entitled Weeds Among the Wheat, written by a Jesuit priest with many years
of experience as a teacher and counselor.

Even if you are in one of the non Roman Catholic Christian traditions, there is
much in the book that can be extrapolated.
One major principle is that God works through relationships, rarely if ever against relationships -- if those relationships are in and of themselves
in alignment Christ.
If you are married and your marriage is going well, and especially if you have young children (dependants) or older parents in your care, a seeming call
from God to leave your marriage and abandon care of your dependants to go
carry the Gospel on the open road -- that is a call that must be taken with
suspicion.
Where it gets interesting are situations where there are weeds among the wheat --God is close and one's ego (or the Adversary) tries to contaminate the leading.
One example Father Greene gives is of a situation where you are in prayer, God
is seeming to feel very close -- and you are interrupted with an urgent message from a housemate or supervisor.
If you're angry that you're being taken away from the sweetness you've been savoring in prayer, that is a clue that ego or the Adversary is horning in.
If, you are not at all resentful of the interruption and smoothly transition to
what someone needs you to do -- that's a pretty good sign.
A truly good test is seeing whether, long term, you are becoming more patient, more resourceful, better to live with and work with.
