Always a positive symbol, though at times it can represent a warning.
If you yourself are following Jesus, wearing period garb, and actually observing his work, this could be a past-life memory, especially if the dream is especially vivid. Be sure and write down every detail you remember, because the dream is actually telling you a lot about you as well as about Jesus.
If Jesus is speaking to you in the here and now, again, when you awaken, write down everything he says that you can remember.
It could be important.
If you see Jesus coming out of the sky, as in the prophecies of the Rapture, some momentous event is going to make a very major and positive difference in your life. If you see Jesus speaking with other Masters – such as Krishna, Buddha, and Mohammed – again, write down what you hear.
This is a message that can make a big difference to your spiritual progress
