Dreams and realities

It has been really bizarre how much I have dreamed over here and how much that impacts my mood. For e.g last night I dreamt about all of my family and I had left my car at my brothers place and then as I was waking up I realised - I couldn't have because I am in England and I can't pick it up. And then again - I sold my car - so I couldn't have driven it there or left it there!
And i woke up in a really sad way. Realising that I was lonely and didn't have my family just around the corner to rely on. I also dreamt vividly about my nieces and nephews and realised that I had a real gap of having no children over here - to muck around with or even just to hug! And that left me feeling really sad as well.
So the day before i was ok, then after one dream I can feel really alone and down. Things will only get better.
