Bugging nightmares

H has been having nightmares recently. He would wake up in the middle of the night shouting for mommy. In all his nightmares, there's one recurring theme - bugs! First it was spiders, then ants, then bees, and last night cockroaches. Usually it's about him being attacked my the insects (I think). I try not to ask questions so as not to disrupt his sleep. Normally I'd just reassure him that there's no bugs in his room and that mommy is here.

Normally dreams or nightmares occur when your subconscious mind is trying to make sense of your emotions or the things that are happening in your life, whether you know it or not. I'm beginning to wonder what is actually bothering him for him to be getting these nightmares.  A quick googling revealed that dreaming about insects often indicates that something is annoying or pestering him/her. It further revealed that if a person dreams that he/she is completely surrounded or overwhelmed by insects, he/she is probably so annoyed by something or someone that he/she is ready to freak out. Oops, this sounds like the subject of H's dream. Should I be concern?

Here are interpretations of the said insects from H's dreams (from my google research):

1. Ants: It could mean that the person is feeling "ansty", or ressless. Ants also can symbolise the small annoyances and irritations in our daily lives.
2. Bees: Bees are usually a good omen, they symbolise wealth, good luck, harmony, creativity and bliss. However, if you get stung by one, it may indicate that you have been wronged. Maybe you have been hurt by some stinging remark.
3. Spiders: To see a spider in your dream indicates that you are feeling like an outsider in some situation. The spider is also symbolic of feminine power or an overbearing mother figure in your life. However, if to see a spider spinning a web in your dream signifies that you will be rewarded for your hard work.
4. Cockroaches: Dreaming of cockroaches generally means there is a part of your life you feel you need to confront and possibly change. It can represent a need for renewal or self-cleaning of your emotional or spiritual being.

Apparently dreaming of bugs is one the top 10 nightmares among children. I'm not sure if that's supposed to be reassuring, i.e. everything's normal and there's nothing to worry about. According to Dr. Gillian Holloway in her article "Your Child's Top 10 Nightmares and Dreams Explained", children are prone to dreaming about insects in their bed or a swarm of bugs coming into their room at night (sounds very much like H to me). I quote from her article:

"What you need to know:
This is a dream that may recur a few times with varying degrees of agitation. It is a common dream for youngsters to experience when they are facing unpredictable situations, such as a separation in the marriage, moving into a new home or a new sibling being brought home. There is no single catalyst or interpretation for the attacking insects; rather, the frightening dream seems to reflect a sense of bewilderment and being overwhelmed. Arguments, unexpected changes and feeling as if she has no control over events may trigger repetitions of the dream. If your child has this dream, do what you can to give her some sense of control, or at least a voice in her own fate. Point out stability where it still exists, and help things to be as smooth and predictable as possible. And do what you can to manage your own anxiety, for she may pick it up and feel unsettled even though you aren't saying much about the situation."

Has this all to do with H trying to adjust to the big school?
