i would suggest you start by laying down flat. relax your body and your mind, clear your thoughts(im sure you might have heard that before)
and start to slightly tense up one muscle at a time from your toes all the way up to your neck. this will help you become familiar with energies.
you could also try to awaken your third eye. one way i do that, is by lighting a yellow candle, closing my eyes, and push energy to that specific chakra.
I agree with Tethaia. Start by meditating. Laying down, relaxing, and just breathing. Breath in deeply through your nose, hold for a few secs, and slowly breath out. I would also add crystals in this, and to carry it around with you. I recommend an amethyst, or a lapis lazuli, or a moonstone, but whatever you feel attracts you. If you need anymore info on crystals , mail me. Another thing I recommend is to develop your third eye chakra. Again, lapis and amethyst are crystals for this. If you need anymore information in detail, please mail me. Good luck :)
You can develop your Psychic powers through thousands of methods...even your own method. Meditation is good, then you can apply a technique that is a bit harder and go from baby steps into adult steps if you are following what I am saying. I try to stare at a picture at times..and visualize everything about the image...the color...Everything. Using my five senses. Having a very visualized imagination about the pictures. Using my smell of it including.
