I do when my third eye chakra is closed or almost closed....when I don't use my gifts and come away from my spirituality for awhile, I find that when I meditate my third eye almost hurts. Maybe you are closed off there, and therefore it will be slightly uncomfortable....but the more meditation you do, the more open you will become.
Quartz, Rochelle salt, and tourmaline are examples of crystals that exhibit the piezoelectric effect when subjected to pressure. When pressure is applied to these crystals, they generate an electric charge proportional to the amount of pressure applied, which can be used in various applications such as sensors and devices.

Yes, pressure can cause long mineral crystals to align in a process known as foliation. This alignment occurs in metamorphic rocks under directional pressure, which causes the minerals to grow in a preferred orientation parallel to the direction of pressure.
It depends on the mineral and the pressure and temperature at which it forms best.
The term is piezoelectricity. This phenomenon occurs when certain crystals, like quartz, generate an electrical current in response to mechanical stress or pressure being applied to them.
When pressure is applied to ice crystals, they may melt and transition into water if the pressure exceeds the melting point of ice. This process is known as pressure melting. Under high pressure, ice can also transform directly into water vapor through sublimation without melting first.
Metamorphization-the process of heating and putting stone under great amounts of pressure. The slower the rocks cool, the larger the crystals.

The crystals will always form according the geometric parameters of the mineral crystal system to which they belong, but the size of the crystals varies depending on the environment in which they form.
The rate at which the magma cools determines the size of crystals in an igneous rock. Slow cooling allows for large crystals to form, while rapid cooling results in small or no crystals. Other factors such as mineral composition and pressure can also influence crystal size.
Crystals have flaws because during the growth process, they can experience changes in temperature, pressure, or impurities in the surrounding environment, leading to irregularities in their molecular structure. These irregularities result in defects such as dislocations, vacancies, or impurities within the crystal lattice.
