How likely is it, or is it even possible, for an air mass, similar to a small cloud, to form inside a house?

Question

Could a specific air mass inside a house (or castle, perhaps) become dense, or cloudy? What could cause this?

Sometimes, after an afternoon rainstorm, the hot street will seem to "steam". Water vapor condenses around particles or nuclei creating wisps of clouds that look like steam, or smoke. Without outside sunlight, or evaporation, without smoke of any kind, what phenomenon could cause an inside air mass to become cloudy?

Trying to isolate such a phenomenon in relation to ghost sightings.

Any answers, thoughts, or ideas appreciated. Would like to brainstorm scientific and/or alternative explanations, including science fiction.

Examples: temperature, spirits, humidity, gravity wells, life force, gamma rays, x-rays, methane gas, dust, magnetism, static electricity, even a defective alien invisiblity shield...anything you think is a possible cause for air inside a house to spontaneously mass, fog up, or cloud.

If you can, please explain with details. Thank you

Answer 1

A lot would depend on how high the ceiling was. In a gallery that has the ceiling 3 floors higher even higher, it is possible for clouds to form and even perhaps rain fall

Answer 2

When my wife cooks pinto beans we seem to have a cloud in our house, it may be spirits because every thime my kids see them they run out of the house.

Answer 3

Certainly possible.   If air is saturated, 100 percent humidity, and there is a slight drop in temperature, fog will form, which is a cloud.

Answer 4

i get a cloud of steam every time I make pasta.I guess under the right conditions it could travel around.That's a lot more likely then a ghost.Any explanation would be more likely then a ghost,though.

Answer 5

since generally some people do have clouds over their heads, both indoors and outdoors, I suspect they could form while indoors.

Answer 6

yes it is possible based on the design of the house, and if the ventilation is adequate or not, and the air flow breaths well or can be trapped in tight corners.

A famous hotel in Dubai actually rains inside the building lobby, as the air conditioning units creates ideal conditions for the formation of rain clouds inside the structure. It was not by design as the designers did not plan it, it was just an oversight, and now it's even a marketing ploy.

Houses can have similar effects due to unforeseen design flaws.

Answer 7

Hello,, like dry ice? or a fog machine? If you dare ask it to reappear.

Answer 8

If there is a marked difference in temperature between the air and the surface then sure there is a possibility that fog to form.

Are you speaking of something in particular?
