You don’t have to learn to see them, just be where ghosts are. Like

said, go to places where ghosts have been known to be to catch a glimpse. Absent of places you’ve heard ghosts have been spotted, you can find places where they’re more likely to be e.g. places of death, decay, and spiritual middle grounds. So cemeteries, the corpsified guts of rotted-out buildings, and churches. Places of tragedy. Places of memory.
Just be careful. If you go looking, you will find eventually, and not all ghosts are ghosts. Catch what I’m saying? Everyone alive today has no idea what they’re looking at, and there seems to be an entire range of metaphysical phenomena that goes bump in the night. Much of it innocuous or neutral, some of it however is very old and angry.
Evil is real.
Be careful.
