Are bubbles safe for humans?

Excuse me, I'm a bit perplexed about this concept. Could you clarify something for me, please? It's this topic about 'bubbles' and whether or not they're safe for humans. I've heard different opinions, and I'm not quite sure what to believe. Could you explain, in simple terms, what exactly are we referring to when we say 'bubbles'? Are they the kind you see in a bubble bath or something else entirely? And most importantly, are they considered safe for human contact? I'd appreciate your insights on this matter.
