I don't understand economics

There's been a lot of economics on the radio recently:

1. Fear of house prices falling
2. The pound dropping against the Euro
3. Shortage of mortgages

Now I remember a few months ago, it was:

1. Fear of house price rises triggering inflation
2. A high pound inhibiting exports and flooding us with cheap imports
3. Economic growth being fuelled by ever higher levels of debt.

Some contradiction there?
