That's really freaky.

But not to diminish your experience, when these appearance/disappearance/'timeslip' type events happen, they're usually just weird+++.

They usually don't mean anything and don't lead to anything.

We've had a football boot disappear in mid-air, and another time a glass bowl just dematerialised from the coffee table (just melting into 'pixels' and then blank space). In front of our eyes. No intoxicants were involved in either case!
