Brain computer interface (BCI) is something that will become more than reality in next 50 years. Actually the first neuroheadset will be lauched soon (late 2008) by Emotiv Systems.

In the future it might be possible that small nanorobots will scan our brains to see our dreams and feelings. Other possibility is small holes drilled to our skull for special BCI devise. This devise could for example record our dreams, and next day we could look at them in our therapy session. Freud would be so exicted about this if he was alive! (check here the whole story)

This vision about capturing dreams was provided by Michael Anissinov from a blog Accelerating Future. Check that blog- it is great!
