Most of the dust in your house is the dead skin of you and any pets you have.

Apparently Swedish resident Lena Pettersson was none too pleased with having to endure such an experience during her recent aerial adventure. After complaining to Kenya Airways about the uncomfortable situation, the airline refunded Pettersson 5000 kronor, which is roughly half of the price of her ticket.
According to the International Business Times, Pettersson was on a flight from Amsterdam to Tanzania when the man in the seat across the aisle starting looking a little wonky. Despite the fact that the poor guy was sweating and experiencing seizures, the plane took off anyway. Although attempts were made to save the man’s life — one passenger even performed a cardiac massage — the passenger died mid-flight.
Those seated next to the body were moved to other areas of the plane. The flight staff, seemingly unprepared to handle such an unfortunate turn of events, laid his body across three seats and covered it with a blanket. Petersson, none too thrilled with having to spend the rest of the flight seated next to a corpse, asked if she could be moved to a different location, as well. Since there weren’t any available spots, she was forced to sit next to the dead body for the remainder of her trip.
“Of course it was unpleasant,” Pettersson explained to a local newspaper, “But I am not a person who makes a fuss.” When asked about the amount of her refund, she added, “This feels much better. It is reasonable.”>>

Certainly. Indeed, if you were flying through one of these clouds you would not be able to see it, and it would require extremely sensitive instruments to even detect its presence. The particle density inside a dust cloud corresponds to what would be considered a very hard vacuum in any laboratory.
You wouldn't want to fly too fast through it, however:
