Sleepwalking anyone?

On top of all the issues I have to deal with I have now found myself sleepwalking in the night, something I have never done in the past. I first notice it over a year ago and has happened a couple more times (that I know of) until now. In the last 10 days I have done it 3 times; I have found pictures and plants on the floor the next morning without me remembering how the hell I did it. A couple of times I have regained ‘consciousness’ and got back into bed. I lock my door in case something serious happens.
