I want to reflect on my session today and process it but I can hardly remember most of it

. A lot of overwhelming things came up for me and I completely shut down and shut out my emotions. I remember checking my watch and thinking "OMG I can't believe there's still 15 mins to go". I remember bits and pieces but it's all jumbled up and I can't make a lot of sense out of it.
I get this really weird feeling when I get overwhelmed during session. It's like everything goes "fuzzy". The fuzziness starts out in my peripheral vision and starts to narrow inwards. It's not like blurred vision either it's really hard to describe but it has a more "all over" feeling than just a vision thing. I'm assuming this is some sort of dissociation symptom but I'm really not sure.
