This thread may be trying to run before it can walk.
Maybe we could start by devising a test so golfy can prove to himself he's psychic (or not)
Yeah, I know he's absolutely convinced that he is, but he lacks rigorous proof. So how about a simple test that doesn't involve any receiver potentially lying to golfy:
Find yourself a nice spot like a park bench where you can sit and watch people passing by a litter bin. Choose one that's not so close by that they would be aware of your watching.
Now every time someone passes it, you project "there's a £20 note in that bin" to them. Or "there's a kitten..." or "there's a gun...", or whatever you like. (Is that the kind of thought projection you think you can do?)
Time the session and keep score - a tick if they look in the bin, a cross if they don't.
Then for comparison, time and score a second session where you don't project a message.
If you find you get a significant hit rate of people looking in the bin, please let us know. If you don't, please let us know that too.
After that, if you were successful, the obvious next step would be to repeat it with a witness.
If you were unsuccessful, I hope your next step would be to very seriously consider if an illness might be making you believe things which are not real.
<edit to add> There would be a temptation to award yourself a tick if people glanced at the bin, or kinda looked as if they might have looked in that direction. Resist temptation - only give yourself a tick if they go out of their way to look in the bin.
