So my bedroom door keeps opening by itself. Usually just a little, but the other day it's been doing a lot. I'm atheist, I like to believe in science. Although I do have a tiny spiritual side. I'm jusr wondering if it's normal or...?

My house is very old and the doors always swing about. Some of the windows aren't what you'd call a great fit either, and will rattle a bit or swing. Openning an upstairs door will often affect some other door. Draughts from the chimney do it, and when a fire burns low the change in temperature will cause a door to swing too. Also hinges on doors wear over time, we don't tend to have spring loaded doors like offices and things in our homes. If one hinge 'drops' or becomes a little loose it shifts the weight too. And that door will then tend to either always swing to open, or just the opposite and be impossible to keep open without a wedge/door stop. Have a look at your hinges, where they joing the back edge of the door to the frame. If a latched (or even worse, locked!) door opens itself then it's probably time to worry. If I saw the knob or handle turn and the door open itself I'd pretty well have a nervous breakdown I reckon. But I've never seen anything like that happen. Don't want to either mate!!
ps. Regarding science, the service and lift-shafts in very high skyscrapers would cause upward convection currents in the building as strong as a gale-force winds if the architetcs and engineers didn't use tricks to limit them. So we're talking about a real, proven, and entirely natural forces here. [ rainhorse68's advice column | Ask rainhorse68 A Question ]
adviceman49 answered Monday September 14 2015, 9:11 am: I can explain what is probably happening using science and one word, "Convection;" The theory of air movement from warm to cold or cold to warm. This is how must of us heat or cool our homes through CONVECTION.
Because we use convection to use our homes there is always a slight current of air movement in our homes. Then add to this any real differential pressure between indoors and out and the current of air movement can increase which could cause your door to open more. If it was windy out and the wind was coming from just the right direction your room could have been slightly more negatively pressured which would allow for more air movement into your room. This air movement is something we are accustomed to so we hardly notice it.

what i mean by this is:
Odd cloud formations
Birds falling out the sky and dying
antelope just keeling over and dying out in the middle of nowhere and crews having to collect the bodies and get rid of them.
and lastly about factories in china exploding or looking like it was hit by a missle when nothing came from the skies and there was video footage to prove it.
