Stray voltage question

[JJ-MIK]

Ok. I just measured the voltage from the ground. I am getting 34 volts. And can anyone decipher this one.. One probe in the water. And the other probe I touched the metal stand. It read 3-4 volts. I stuck the probe in the carpet and it read 3-4 volts.. Is it just because everything is touching? Is the considered a complete circuit?

And then here is what is confusing me now.. Everything unplugged.. I'm getting 40v from the ground. 1.0 v in one prong. And 102 v in the other prong... Is this a house electrical issue??

Just checked my tank downstairs . I believe different circuit. I'm getting 12.8v in ground. 12.8 in one prong. 28.8 in the other.. I think I need to call an electrician....
