Finally got the damn camera thing done (actually I did it a week ago but haven't had time to write it down). Here's the dream:

I am outside our house. I go for a walk. While I'm walking I look at the stars. I see some big galaxies. I realise that you can't see galaxies with bare eye, so I must be lucid. This time I'll get the 1900s task done. As teleporting has ruined my earlier attempts at the task, I simply decide I am in the 1900s. The street lights and the houses turn to look like ones from the beginning of the 20th century. I go into one of the houses. The house is very narrow and has 2 or 3 floors. I go to the bedroom. There is a woman there. A box appears into my hand. It has a button on the top. I take a picture of the woman sitting in the bed. The image is black-and-white. If I remember right, the woman had a black shirt and a curly blond hair. There was also another woman in the room but I don't remember anything about her.
