Is the gift to see the spiritual realm and visit heaven and hell still possible for today?

I have been hearing a lot lately about people who have seen angels and demons in the spiritual realm since they were young. They have seen places in hell and seen God and Jesus Christ as well as the disciples and many other biblical characters. They also claim to have gone to heaven and hell numerous amounts of times and see different things. Is this real? Is this gift for us today? How can we have this gift as believers?
