Im not sure what they could ahve been from. MIL asks what could a 9 month old possibly have nightmares about...but then i think well:

1. Needles she's had (even tho they reckon babies dont remember that)
2. Her birth
3. Falls, accidents she has had
4. Getting in trouble
5. Raising my voice
6. Cats may have scared her

Heaps of things....noises and actions. Not to sure though. But its not fun when it happens!
