Most people are in contact with spirit guides whether they are aware of this fact or not. Here are some examples: You are in the shower enjoying the wonderful sensation of warm water pouring over you head, when all of a sudden an insight flashes helping you to solve a problem at work.
Or you happen to be a song writer and mostly you plug along at crafting your music, but this one time a new song comes so fast to you that you need to grab a piece of paper and write it down as fast as you can. Because it is coming to you, rather than coming from you.
Or your decide to drive the long way home, only to discover that there was a terrible accident on the road you normally take. The list of examples are endless. We are being helped by beings in the spiritual realm frequently. Pay attention to when an idea comes to you instead of from you.
