Kids at early childhood places can scare them too - they can get ideas from what other kids say and do when playing (especially boys who like to scare them and talk about fighting and shooting and cutting and monsters!).. icky boys!).
Paris started talking about werid things.. about 2 or 3 months ago, she one day screamed really loud and suddenly came tearing down the hallway after playing in her room happily, talking all about a black monster that had gone under her bed. She could describe it, and said it had stood there and had it's back to her and then went under her bed. we went through all the things of "was it a spider?/a fly/shadows,imagining about dogs, maybe she saw something out of the corner of her eye as she moved etc" she got angry at us because she thought we were making fun of her, and we searched under her bed, and showed her nothing was there. For about a month she wouldn't even go in her room cos "the black monster" was in there, we had trouble at bedtime.. she wouldn't even go up the hallway without one of us with her. We just kept reassuring her and teling her that mummy and daddy were here to keep her safe, that monsters are make beleive and there was nothing there, and bit by bit it slowly faded out, cannot remember the last time she actually said about it and she happily plays in her room again no problems.
So yes, they get weird anxieties.. just keep doing the same as you always have and she'll know theres a safe base to always return to, the same routine etc, Reassure her and ask her why she though these things are going to happen.. sometimes it's good to nut out what it is that made them make that connection. Ie do you ever say to her when she's going down stairs "be careful not to fall" or something like that?.. at this age they also get concerns over other people too cos they start to realise theres a whole lot more out there than just their own little world
