What you are providing is an anedoctal thesis, wich is fallacious for three reasons:
- We have no evidences that what you are saying happened, now i don’t want to call you a liar, but with 0 proofs in support of what you are claiming your argument already starts badly.
- What you claim is simply absurd: “These are objects wich have arrived via teleportation”, no offense, but it’s just absurd to think that objects teleport through wind to you.
- There is certainly a logical explanation to this, every single anedoctal paranormal story has one: for the first case we can simply make the hypothesis you simply had more change in your pocket and didn’t realise, you thought that you had emptied your pockets, but had more and this entire story is simply the result of a completely normal and human mistake; in the case of the scar it might be that it was a simple bruise that just healed like every other bruise after some time. Please keep in mind, i am not saying that these hypothesis are true and the only correct one, i am just saying that are more plausible than magical coin teleportation or magic healing.
