It's like a straw in a milkshake. If you suck hard enough, you see a dimple form around the straw.
Water is pulled out of the ground which leaves an air pocket in the space around the soil particles. Any nearby water around the air pocket flows into it, but it can only flow in the cracks between soil particles so it takes it a little time to get there.
If the pump is pumping out faster than the water is flowing in, the water table at the pump location begins to drawdown. The surrounding water table slopes down to the low spot which, from the side, makes a cone shape with curved walls.
The more you pump, the larger your cone. Soil with lots of clay in it has very small cracks between particles, so incoming (recharge) water gets there much more slowly. The walls of the cone will be steeper than in a sandy soil having plenty of void space for water to move through. Real ground is never just one kind of soil, though, and things are all mixed up in layers and clumps, so even with a soil test you're still only left with an educated guess as to how deep and how wide the actual cone will be.

A well causes a cone of depression by pumping water out of an aquifer faster than it can be replenished. This creates a lowered water table around the well, forming a cone-shaped depression. The size and shape of the cone of depression depend on factors such as the pumping rate, geology, and the aquifer's recharge rate.

Can depression cause brief psychosis?
Stress can cause Brief Reactive Psychosis, and it can cause Depression as well. so perhaps it can indirectly.
Can depression cause delusions?
Depression can very well cause delusions. But when this happens, it no longer is depression. If your seeing things out of the ordinary your depression could have turned into something much more serious like, physcotic depression.
