Yes, actual angels and demons are walking among us. Sometimes both types of angels influence us via visions or whispering into our hearts and minds. Some are warnings, some are enticements to temptations.
When demons do that, those are evil thoughts we must conquer, for they are real entities that strive to disrupt our lives and cause us to sin. They want you to suffer and they strive to cause you to make others suffer. More than anything they want to erode or eradicate your belief in Jesus Christ. That's the bad news.
