Interview of the affected scuba diver
Interviewer: Dr ███████
Interviewee: Johan Eriksson
Foreword: Johan Eriksson was the first to be affected by SCP-XXXX, so the foundation wants to know more about the
incident.<Begin log>
Dr ███████: So, how did you and your partner find the SCP-XXXX?
Mr Eriksson: We were scuba diving in the area because we wanted to find something interesting. We heard that the
area was full of intriguing stuff so we went there. We dove for about half an hour when we found the remains of what looked like a submarine. Of course I was
interested in finding out what the inside would look like.Dr ███████: How did the inside look like?
Mr Eriksson: First it seemed like what I imagined: Rusty, dark and full of sea plants. Then I started to feel light headed, but didn't think much of it. Few
minutes in the feeling got worse and I was just about to dive out of there, when I saw
something: A person standing in front of me speaking. I wasn't scared. In fact I felt totally calm and relaxed. Then I started
to hear the apparition talking in German.Dr ███████: What happened then?
Mr Eriksson: I saw the ship start to look new and functioning. I could hear sound of the engine and people shouting. It felt calming for some reason. Then I my
partner grabbed me and dragged me away from the submarine. Last thing I
remember is the sound of the people getting weaker.Dr ███████: So you don't remember being in a "trans-like state" like your partner mentioned?
Mr Eriksson: No, I don't. The next thing I remember was me lying in my bed on our ship.
Dr ███████: Thank you for your time, Mr Eriksson.
