Welcome Synne! 
You may want to introduce yourself to the community in the big “Hi,I’m new” topic ^^
Definitely sounds like an OBE to me. But congrats anyway! 
It was a good first experience in any way.
The things you should think are the same of when you fall asleep normally, because that’s the way you fall asleep; only to perform a WILD, you stay conscious and detached from your thoughts, using a gimmick of sorts like counting or feeling your breaths, or listening to the buzz i your ears. My mind wanders a lot while I do a successful WILD, so no worries 
Good luck for your next attempts!
