In the name of Allah, the most Beneficent, the most Merciful.
Answer
Imam Taftazani (RA) has said that it is possible to see Allah (SWA) in ones dream and this is something that has been related from many pious predecessors (salaf). However, this “seeing” of Allah is a type of observation (mushahadah) by the heart rather than the eye.” (Sharah al Aqa’id p.76)
The conclusion to your question is that it is possible to see Allah (SWA) in a dream.
