Weed, Schitzophrenia or aliens.
It's a good point about weed. The times I've caught glimpses of something bigger (like supernatural presence) I've been pretty baked. It all seemed quite real at the time, ha. In fact "presence" seemed so palpable even down in my bones that to doubt it felt absurd and extraordinary. But sadly I think it's delusional. Wake up again and poof "presence" is gone again. Coy god. God of shyness. Weed and shrooms certainly provide a tantalizing loosening of boundaries and possibilities for seekers, however.
