internal communication stops when i pay attention

so today i noticed that i was listening into an internal conversation/argument between two parts. but when i started genuinely paying attention to what they're saying (because i wanted to type it into my journal), the conversation stopped and i couldn't reach out to them to ask questions

additionally it also became difficult for me to remember what they said afterwards (this happens every time i notice any communication)

whenever i try to consciously(?) reach out to other parts i'm met with silence, but they can randomly chime in on what i'm doing/thinking or even have conversations between themselves, and i can't ask them anything

so due to that, i've been concerned that any of the communication i'm noticing is just a daydream... is this a sign?
