My mind hides

Hi Team, it seems whenever it is time to do a thought download I’m having one of two issues. Either my mind just stops, like it doesn’t want to be watched or I’m just not listening hard enough? Sometimes, my mind will just start singing songs. Is this normal? I’m two months in to Scholars and it seems the more I try to start getting serious and doing topic/circumstance specific downloads, the more this happens. If I’m doing a general thought download for the day, I can witness more thoughts, but they often seem superficial. Looking for any insight. Thanks so much in advance!!
