When someone close to you dies it sucks. Even though you’ll always remember them it’s never the same because at most you have a few photos to gaze at.
Who cares if you’re not actually speaking to a real person when you see your dead friends and relatives in a lucid dream? Who cares if some people do believe they’re really speaking to a ghost? It doesn’t matter either way.
When you see someone in a lucid dream it’s more real than looking at a photo because they’re actually there. They can be standing in front of you like they never left, so take advantage of it.
