During your sleeping hours you can pick up on what someone else is thinking or feeling, and even meet them in a dreamscape.
Start making your plans when awake. Imagine meeting a friend at a certain place, and be as specific about this as you would be if you were putting the event in your diary, settling on a specific date and time. Choose a friend who remembers their dreams easily, has an open mind and can be relied on not to forget the experiment. You might like to write down the details, so you are totally clear.
Now imagine giving your friend something unusual and maybe symbolic, such as a big, fluffy red heart or a golden key. Go through this in your mind until you know it by heart. Ask your friend to write down and remember any dream they have on the night you’ve arranged, but don’t tell them anything else. Do not say you plan to dream about them, or even that your experiment has anything to do with telepathy.
Before you drop off to sleep, go through your dream scenario several times, imagining the time, the place and the exchange of gifts with your friend. As you drift off, visualise meeting them. When you wake up, write down exactly what you dreamed – unless you are very practised and/or talented, it will probably vary from your plans.
Then compare notes with your friend. If they are comfortable with this, you may like to still withhold a total explanation. Either way, carry on practising until you do your dream telepathy easily.
