I used to study in the city of Minsk, Belarus back in 1984. I had regular encounters with sentient glowing orange orbs that used to materialise in my hostel room in the early hours. They were extremely communicative – while I was in a sleep state. I’d wake up, realise they were there and I’d been talking to them…..and watch them promptly fly SLOWLY out the window or straight up through the solid ceiling.
Could never consciously remember what we were talking about though. They were definitely real – and no, I didn’t do drugs or drink! -paul
