I dont use plugs any more but i used to, i found a sleep mask that has headphone speakers built in playing an audiobook or white noise is ideal for me.
They make different kinds, some might be more comfortable than others. I am indeed a real person, who has experience sleeping in very loud environments.
A good guess but so far as i can tell they dont actually message people directly outside of the initial contact. The chat rooms are barely active but ive been idling on the matrix for days and nothing.
