Is it epilepsy

Hey, im hoping someone could help me out please. I went for a neurology appointment last month as i have what i call my bubbles. It basically feels like ive gone into my own world im staring and vision can go blury but im sort of aware there is noises around me but cant react im just in a stare that i cant snap out of. Ive been in a conversation where i know there talking to me but its just all muffled and i had to ask them to repeat as i had no idea what they were saying. Ive also been in a convo where ive not herd a thing and they laughed beacuse i was just not with it. Ive had a few dreams in the past year where ive had a seizure and i could really feel it and knew i was having one but couldnt wake up. When i did i felt drained. I forgot to mention the dreams as i was so nervous. The lady dont think its epilepsy but wants me to have a eeg which i have on saturday. She thinks its my sleep but the sleep people said there was nothing wrong.ive been having them since late teens and have gotten worse within the last year and a half too two years. I hope this makes sense. If anyine has any questions and if they could help me id really appreciate it.
