@funfortehfun I am not sure why you would be using such a high shutter speed indoors?
You might need to do some tutorial reading and get a better understanding of shutter speed and aperture versus ISO settings.
Usually, most people can photograph anything that is static, without flash, handheld at 1/100th second and get no blur. Some can shoot at 1/30th successfully if they are very stable. Shutter speed is what freezes any movement and is also what controls how much the ambient light affects your exposure.
Aperture controls your depth of field and controls flash exposure when using flash for lighting.
ISO simply controls how sensitive the sensor is to light but it will cause some grain noise at higher ISO numbers and with bad exposures in low light.
Unless you are shooting something that is moving, be it human or animal or other relatively slow moving object you should not need more than 1/250th second shutter speed to freeze motion. With birds and other fast moving things you would need anywhere from 1/500th to over 1/2000th depending on what it is and how fast it moves.
Your aperture and ISO have nothing to do with motion stopping except that they can be changed to allow for faster shutter speeds.
So indoors, shooting pics of people or animals you should never need more than 1/250th shutter speed at max. I usually use 1/125th when shooting people and pets. Anything that is not moving you should be able to use 1/100th even with shaky hands.
I would suggest setting Auto ISO to allow a maximum ISO of 1600 and a minimum shutter speed of 1/100th when shooting indoors. Then choose your aperture setting according to how much of the image you want to be in focus (DOF) and just let the shutter speed and ISO choose itself. If you get too much grain/noise in your pictures then set auto ISO to a maximum of 800.
