For the past few nights DD (8) has been having nightmares

There were 2 in particular that have really upset her.

1 - I collected her from school and was heading towards the car when I turned and looked at her and said 'Sorry, you are not part of the family anymore' ...

2 - Last night she had a dream an alien with a big head killed her. She showed me a pic of the alien and it kinda looked like a bub in the early weeks - BIG head and small body.

It got me thinking though - Can she sense something? She has had bad dreams before, but never to the point shes crying at my bedside wanting a cuddle.

DP and I have been spending ALOT more time with her the past few weeks because she is on holidays.

Thoughts?
