Do microscopic black holes exist? Yes Ball Lightning Comets Sunspots etc.

Micro black holes, also called quantum mechanical black holes or mini black holes, are hypothetical tiny black holes, for which quantum mechanical effects play an important role. The concept that black holes may exist that are smaller than stellar mass was introduced in 1971 by Stephen Hawking.

The (Q-FFF) Theory of Everything (TOE), is a Compound Rigid KNOT THEORY constructing even Black Holes (and micro BHs: Comets, Sprites, Sunspots), postulating the Charge Parity symmetric Entangled "Raspberry Multiverse" which could be called Telepathic as a base for uncertainty (ER=EPR) and Libet's consciousness measurements (RPI and RPII).
