I wish I could get premonitions. The closest thing to telepathy that I have had is, I sit next to my friend and I ask him what I am thinking. Depending on how clear my mind is feeling that day, it can be very successful or only a little. If Iam thinking very vividly he can guess things as specific as "magnum rifle" or "pickup truck". It's really cool.
Also, when I call my friend and he comes over, sometimes he has a few things to do before he comes over, so the length of time it takes can vary greatly.
The last two times he came over, I was in the basement and sensed he was right outside my house. So i went outside and yep, he was right there.
From what I have read about astral projection, I suggest to you that you try and focus your dreams on the future, or islam if you like. It can help to think a lot about these things right before you go to sleep, because the chance that it enters your unconcious mind is higher
