Tbh I'm surprised that he didn't have any superhuman strength and that he couldn't just beat them up alone. That dream part kinda gave the impression that maybe their bodies are above human also. Not really sure if this is the better or worse for him being a guy you can gang up on..
Also I thought that their confidence (/chill attitude) to travel into past/different cultures, was that they are able to fend themselves if needed. Now it just makes it seem that every trip to past is extremely risky and a gamble, for them not meeting bad people who might want to fe. murder/rape or do something else as horrendous to them.
