Yeah, the pillow cube probably wouldn't be too comfy that way.
I keep waking up at various weird times because I keep thinking I'm hearing somebody going "Pssst!" whisper-like in my face like somebody trying to get my attention. It's really creepy. I'm assuming it's a hypnopompic hallucination, which I've had happen a time or too. Who knows, maybe it's me making the sound and waking myself up. Always happens after my husband is gone, so it's not him. The sort of creepy part is it sounds sort of like him, though.
