((((((((((((((((((( Tree ))))))))))))))))) maybe you are unconsciously giving yourself a break. Could be that you really need it.

If it is worrisome to you that you don't remember last session (this happens to me too sometimes), you might journal it a little, that same day or evening, and maybe it will come back to you. If not right away, maybe later.

One thing for sure, below our conscious minds, things are working away 24/7, so nothing is lost really. still it must be disconcerting at least, and maybe scary. I hope not scary.
