The trouble with communicating with spirits, many a time, is that they don't communicate at the same speed as the living. Most spirits communicate with pure thought, as they don't have bodies - they exist on a different plane of existance than we do. They exist as energy, as spirit. They don't need to take big breaths of air to scream!
Spirits need to consciously slow themselves down in order to be heard easily, but usually they don't -as usually they're excited that someone living can hear them, and they want to say everything a.s.a.p.! This can cause problems for normal people, and psychics/mediums, as they experience the communication as a blitz of words and images.
Many times I have been confronted with this, and this is a source of great frustration on both sides of the conversation. Seeing Mediums, sometimes they'll blurt out words of what they see in sequence: it's not because they're bad Mediums (well not always) but usually it's the spirit that's making the discourse very difficult.
So what can we do about this? Here are three suggestions.
1. Well it's good to let the images come and try to drown out any exterior distractions. To pay close attention, and just let the flow overtake you. After a while you'll learn to just let the thoughts and sensations wash over you and leave you with a general impression. That general impression can be worked upon by delving individually into the images. This is harder to do in a live person-to-person reading, as you will spend a lot of time starting off into space and looking sleepy... hehe
2. Tell the spirits to slow down, you may get lucky and find a spirit who will actually oblige you!
3. Blurt out all the things that come to you, and have someone write it down - or record it if you don't have anyone there to write it down. Then, like a dream you want to remember, go through each detail you recall and things will start unlocking themselves. Blurt out ANYTHING you see, as they may have significance to the person you're doing the communication for.
I hope that's helpful!
