See: It could be that there were a lot of things that happened on that day which I do remember and a lot of things that happened which I do not remember.
In this sentence, I think COULD BE must be changed to COULD HAVE BEEN, because to refer to a possible past event, the tense to use is COULD HAVE DONE STH, while in the sentence the meaning is referring to a present thing. But I can't be sure; could you help me?
No, 'could be' is correct - it is referring to remembering in the present, not the things that 'happened that day'
