Voltage and current in parallel circuit

I am having a bit of a tough time understanding the following:

|____O____| <-  0A
|____O____| <- 12A
|____O____| <- 24A
|         | <- 36A
|_[|||||]_| <- 36A

Legend:

O       - A small lamp with 1Ω resistance.
[|||||] - A 12V battery.

There is 12V flowing across each of the lamps and with resistance of 1Ω, and, therefore, there is 12 Amps of current flowing across each one. So, if the current is flowing from right side, up, over and down the left side, there is a total of 36 Amps flowing through the battery itself to supply the three connected lamps. At the top portion of either side of the top lamp (above the points where middle lamp connects) there is only 12 Amps of current; to either side of the middle lamp (above the points where the bottom lamp connects) there is 24 Amps; and to either side of the bottom lamp (below the points where the bottom lamp connects) there is 36 Amps.

Does it mean that a battery that could not shock us, could in fact if we connected several lamps in parallel circuit to raise the amount of current flowing through the circuit at the bottom portion? I'm just trying to wrap my head around circuits and electricity and this popped into my head. I've looked around, but couldn't find a clear answer to help me understand.
