so i took a mini kitchen burner to glue 2 pla pieces together without a mask and 30 minutes later i suddenly started feeling dizzy. is it the pla? or is that something completelly else?  

There's nothing in pure PLA that will give off fumes that you won't get from making popcorn...

If the filaments contains additives there might be small amounts of other fumes but they are unlikely to be in dangerous quantities.

The gas in the burner is a more likely culprit, especially if combustion is incomplete.

So:  It's probably something else.

Cheerio,

thanks diem. 

so its either the butane gas

or

me watching the printer while doing a squat with tilting my upper torso to the ground cause the printer is positioned very low. sitting in normal squat doesnt let me see the nozzle, i have to tilt forward and down, so my head was in a very ackward position.
