Experiences - Confused: Cannabis Induced flashback?

[Whalebale]

back story
i was prescribed a paxil for anxiety last year, and i took lsd two weekends in a row 2 hits each time march 10 2008 and march 20 2008. both times i didnt feel it because of the medecine i was on.
i have been off paxil since august 2008 (going on 9 months).

last night i smoked pot with my freind in my back yard for the first time in 6 months. i took one small hit and just let it settle. i was trying to figure out if i was having a flashback or not. i looked at my dog and he was gnawing on a stick and it looked kinda scary. i remember feeling intense. and i also remember feeling restless and i felt as though my pupils were dialated, but when i looked in the mirror they werent. over all i felt completely numb. it took me about 2 hours to feel completely normal again.

before paxil i used to smoke and enjoy it. yesterday it sucked. to my freinds on this forum. does this sound like a flashback? a regular weed high? i dont remember weed highs feeling like this before i took acid. and that was one year ago.
