Thank you Alex, I'll try that.
Curiously, a few minutes after posting the message, I felt a tension release so I did another HTT session. Got clear images, without much anxiety and then, before looking at the question I spent 15min (usually I give up after 5min) trying to figure out what the streams had in common.
I wrote down all the out of context stuff I got. That helped me to realize a few details that would have scaped if I didn't spent those 15min. Anyway the streams didn't make much sense and had only one thing in common.
I'll report back in 10-12 days.
