Subject: Can a crystal's vibration affect human brain waves?

My mom has a big crystal.  She says that the high vibration of the crystal can
increase the frequency that her brain vibrates at.  What frequency does a
crystal vibrate at?  What frequency does the human brain vibrate at?  Can
something vibrating real fast like a crystal affect something vibrating slower,
like your brain.  My mom says her crystal is like a computer that stores
information.  Is that possible?  It's real big and it doesn't have any metal
parts or anything that would make it work like a cell phone or a computer?
Thanks for answering.  My teachers don't know how to find this stuff out.
