Since I was young I, occasionnaly, have an odd thing happen to me. Something will play out in front of me and I’ll immediately get a strange sensation – a sort of “spidey sense” tingling – and an immediate realisation that I’ve seen this exact scene in a dream (despite not having remembered dreaming about it until that point – don’t ask, I can’t explain it myself).
When I was younger I thought I was having premonitions of the future (albeit, really crappy ones) but, as logic kicked in, I disregarded that, whilst never really knowing what it really was.
I still don’t but, today, I have a name for it.
